Hello,


i think I got a virus. I was on Firefox when my computer spontaneously shut down. When I try to restart it the computer tries to restart but then shuts down again within a few seconds. The computer doesn't even have time turn the screen on again before it shuts down. Please help!

Configuration: Windows XP home edition
Firefox 2.0.0.14

Hi, my laptop will not start either. A few months ago something was spilt all over it, since i dried and cleaned it out its been working relatively well. Then all of the sudden nothing. The lights turn on and the fan goes but nothing no startup. I cant even get to the dos mode. I have an HP G60. Any information or tips you could give me would be very appreciated, I'm at the end of the line here.
Thanks a lot,
Ty

I had an HP for 1 year and the same thing was happening to me. i took it to Best buy and the guy told me it was most likely the mother board. so i called HP and they said the estimate to fix it would be around 300-400 dollars. ive read alot of reviews and sometimes even after you send it to HP,something still goes wrong. i figured that it would just be best to get a new laptop

Hp came out a lot of laptops with the same problem, I have the same problem sometimes and what I do is take out the battery and the AC for 15 minutes. After that I put both back. turn on your laptop and it will turn on. Also you can verify with hp if your laptop has limited program warranty. This a kind of program that they can repair your laptop for free. but the laptop has to pass some requirements.

Most probably the motherboard or the graphics card. Call HP and ask them for help, although don't expect it to get fixed quickly! I had the same problem, brought it in 6 weeks ago and still haven't got it back. Apparently they've got a motherboard on backorder and it still hasn't arrived.

Hey!

I'm having the exact same problem with my HP. Lights com on and nothing else happens... I truned it off and on about 40 times on saturday and finally it booted up. Do you have any idea what's causing thins?

How is yours working now? I'm just keeping mine in standby and hoping i can go a few months withough shutting it down... I've restarted it a few time (installing updates) and it turned back on no problem.

I have a feeling it might be a build of dust/dirt inside. I'm going to open mine up when I get a chance.

IF you are taking the battery out and it works - it just means you need a new battery.

HP Laptops I know won't boot up if the battery is dead (even if you have it plugged into a power source)

In case it might still be useful, check the links below. Make sure you do check the second link where, with your lapatop part number, you can see if yours is covered by HP Limited Warranty Service Enhancement, which goes for 24 months after the start of the initial warranty. Good luck.

I have a presario HP laptop which is less than 1 year old. I was on the internet and it froze. I managed to turn it off by having to disconect power and battery. When i tried to turn it back on the fan would sound, the lights would come on and then after a few seconds it would turn itself off. It would then repeat the process again and again. The screen would constantly remain blank I took it to PCworld who believe it is the motherboard. Does anyone think that this could be a correct diagnosis or should i be trying something else?

Hi, i've been having the same problem for about 7 weeks now. I have try a number of solutions, however, i do have to agree with PC World and say its the motherboard! I have tried all the software solutions to no avail and also hardware! I am not sure if the Bios may need flashing, however. if that does not resolve it, it could damage it more. Failing that, anyone no were to buy a motherboard from....:)

Karen, if you've got one of the 2-9000 v or dv series notebooks you may be experiencing a common problem of motherboard failure. HP and nVidia are addressing this issue by providing a one year extension on the warranty for a free repair. Check out this liink: http://h10025.www1.hp.com/...

Just reading your problem with your HP laptop, I had exactly the same problem,the computer tech's told me the mother board was cooked,i took the mother board out which is easy placed it in the fridge for a few hours,then put it back in the laptop,pressed start and it powered up, its still going,I nearly threw it out and bought a new one,
just goes to show even us amatures can work through these things,

Tony -

Just today, my HP laptop just wouldn't boot up, when it worked fine yesterday. No lights, no screen ...nothing. I took the battery out and put it back in ... still nothing.

I read your advice about putting the mother board in the refrig. what does that do? And which door on the underside of the laptop is the motherboard?

Is there a way to troubleshoot the problem myself, or do I need to take it in somewhere? If so, how do I know the techs are qualified?

Thanks
Janet

Tony, on Feb 14, 2009 1:14:55 am GMT

Hi Janet,
Just read your email,now before you do what I suggested putting the Motherboard in the Fridge I would like you to try this first,
find a small object that you can place onto you on off button,place it on the button then gently close your laptop until it starts,leave it like this for about half an hour,the weight of the lid is enough to hold the button down,the laptop will continue to try to boot up repeatedly,in this time you may see it start,if not after half an hour take out the object you have holding the button,then straight away press start again,
Let me know how you go Janet,if it does not start we will go to step two,
Have a nice day,Cheers Tony.

Whenever I close it when I'm done with it and come back to go on it, it is a black screen but has all the lights on so I then have to restart it and it usually takes it anywhere from 10-15 different tries to sucessfully start up and then when I go on firefox it won't remember any of my passwords or anything. I have to do this every single time I want to use it any suggestions? thank you! :-)

Same problem with an HP Pavillion dv9000 laptop. I took it out in the cold garage, blew it out with the air compressor, took it back in and it started up. Before that couldn't get it to power up on battery or AC, blue lights would come on, it would make a little noise for a few seconds, and power off, no bios/os/screen at all.

hfgslb2, on Jan 30, 2009 12:08:00 pm GMT

The dv6000 has a SATA harddrive and the Gateway has and IDE/ATA. The connectors are different and I'm not sure that you could open the ATA on the dv6000 system or vice-versa. How did you intend to access the info., from a 3rd computer? You may be better off going to a computer store and having them move the info to a cd/dvd for you. Otherwise, you will need a 3rd computer with external enclosures for each harddrive (though you can purchase an enclosure that will come with an adapter that would allow you to install either SATA or IDE/ATA. It's my understanding, though, that a computer set to run and recognize an SATA harddrive will not recognize an IDE/ATA harddrive, and vice-versa. Hope this helps.

I have a dv5000 and I have over the last 2 years had the no boot issue also at least 6 times??? It either just sits at the windows boot screen, or it gets by that and sits at the black screen?? The only way I can get things working again is to do a complete restore, and then I don't have any issues at all for at least a few months?? Seems like it's software related, if it were hardware I shouldn't be able to get it working as good as new by reinstalling the operating system. FYI-- I just did a complete restore last night, and it's working beautifully once again... Any ideas here would be great !! thanks

Howdy yall,

There is a serious issue with the GPU used on a lot of these series notebooks. The trouble resides with the fan being tied to the CPU and allows the GPU to overheat because of this.

-HP claims the problem is a simple fix. 1. If your warranty is still in effect you can send it in. 2. They are going to flash the bios using their BIOS driver update. So you can too by going to their website and using their BIOS driver update (as they call it.)
-Or if your warranty conveniently expired beyond their extention which I had not read about until it croaked. You can still do #2.
-Or worse yet. You're using Vista. It tried to update. It failed and buggered up your harddrive. Now you can't run the driver update because it ONLY works in a windows environment. "
-So here's a list of things you can do... IF you have experience with computers and a loving caring friend with the same type of harddrive your now dead HP uses you can have him install the program on his hdd move it into your computer and install it on the random chance it starts up.
-But you don't have that friend. Get a live copy of linux (let's just say UBUNTU) and load the WINE environement and then find a miracle way to configure it to get their stupid piece of software to install the much needed driver. Then email me because I couldn't do it.
-None of that makes sense? Well shit, take it to a repair shop or call HP and let them charge your an arm and a leg for a problem they allowed to happen. =)

Sorry HP can't/won't help you,

I just finished reassembling my HP pavillion ZX 5000, But the problem is sill there. Power turns on, blue power lights show up but there is no sign of activity. the screen is dark and cant even get to BIOS. I tested the hard drive on another computer and it works fine. At one point i removed the extra memory and when i replaced it similar thing happened but it worked after 2-5 on/off trials...but this time i made like 10-15 on/off trails, still not working...I am hoping something is unhooked..

Johnymemo - have the same issue. 2 things that might help. I keep getting it to start sometimes and not others. I read a blog which I cna't find anymore and the blogger said to press f1 after it got to the state where you would think it should start. It works everytime for me. The blog went on to say that the problem has to do with the little internal battery on the motherboard dying. No way I could fix that myself but if you seem to know how to do that. Let me know on here.

I just got done updating everything!! Fresh reinstall, bios and every device driver I could find. I let it sit for about 3 days no battery in it, or being plugged in, and it did the same thing again!! It took forever to boot up? Clean install?? After a few reboots it finally took hold and is running super? Yesterday I got thinking it could be a possible ram issue, so I remove one of the ram's and ran memtest 10 times on each ram, no errors.. I am now starting to think that it is possible that the HD may be the culprit?? I think I am going to get another HD load it up and run with it, see what happens. Very easy to swap out too..

2 Things: HP emailed me with a fix that seems to be working! AND they are going to fix my laptop for free even though it isn't under warranty (see all the info below).
The problem seems to be related to static charge buildup (which a few of my friends have had troupble with on their non-hp laptops)

Before emailing HP I tried just about everything:
-Took the whole laptop apart and cleaned the motherboard with this spray cleaner for chips
-Removed the RAM and cleaned it
-Deleted EVERYTHING from the hard drive and put Vista Business on (instead of home premum)
-Flashed the BIOS with that new update and updated all drivers.

The problem is still there...

So I emailed HP and explained it to them. I have a dv2000 (dv2422ca) that is a year and a half old (so 6 months past the warranty). They gave me a temporary fix (pop out battery and unplug, hold the power button for 30-60 seconds, power on with AC power only). They are also going to repair the laptop (I'll let you know if they manage to fix it).

Here is there emai:

Dear Perry,

Thank you for contacting HP Total Care.

From your E-mail, I understand that after turning on the notebook there is no display on the LCD screen of your notebook and also the Wireless card is not being detected on your notebook.

I understand your concern and please be assured that customer satisfaction is very important to us, and I will provide the necessary assistance in this regard.

The issue you are experiencing is due to hardware malfunction with the notebook and for both the issues, it requires an onsite diagnosis.

The issue you are experiencing might be due to static charges present on the notebook or due to hardware malfunction with the System Board. To confirm the issue, I recommend you to perform Power drain from the below steps:

==Power Drain===

I would like to inform you that due to regular use of the notebook, some static charges tend to stay in the computer, and sometimes results in not allowing the computer to start. To solve this, kindly perform the following steps:

1. Shut the computer down.
2. Disconnect the AC adapter and remove the battery.
3. Press the power button down for about 30-60 seconds.
4. Reconnect the AC adapter and the battery.
5. Restart the computer.

Try restarting the computer only with the AC power, without the battery and vice-versa.

Now, I recommend you to check with the issue.

If the issue persists, then it is clear that the issue is due to hardware malfunction with the notebook and for both the issues, it requires an onsite diagnosis.

I have checked our database and found that your notebook is out of warranty. But HP has encountered a Hardware problem with few models of DV2000 series and your notebook is one of them. I am happy to inform you that I would process the request for a mail-in repair service for your notebook.

Please complete the information below so that I can process your request for the mail-in repair service:

Hey I have the same problem with my dv2000. It has started to get worse too! Who did you contact at HP for this? Do you have the email address? Or was it just customer support.

Thanks

My dv2000 much more often than not does not start i.e. screen does not come on, leds do come on & 1 long and 2 short beeps.

Cause: GPU/Heatsink thermal glue failure leading to overheating and dry joints. HP are aware of this problem but will only fix within waranty


Google says >>>>


One long beep and two short beeps indicates that the GPU chip is not working.

I have found that the GPU gum between the GPU and the heatsink is meant to fill about a 2mm gap, but the gum dries out and cracks. When this happens the chip overheats, and the BGA pins on the gpu loose there connection. If you leave the power on after the beeping and block the vents a bit, the GPU/CPU heat sink warms up enough to expand the solder on the BGA pins and make a connection and the laptop will run. But eventually the solder will fully fracture, and a ball may come off and then you are totally stuffed.

Fixing the heat sink does not fix the problem - its the cause of the problem though, so if you do get yours fixed, I would recommend opening it, scrapping off the blue gum, and inserting a 2mm peice of copper plate on-top of the GPU and using siler thermal paste to connect the GPU to the copper plate and then again on the other side to connect to the heatsink. But this won’t fix it if its already dead. (I tried it and I get the same long beep, two short beep).

To fix the problem you have to re-flow the solder on the BGA. This should be done as a last resort (after your laptop doesnt turn on any more even when you heat it up). You have to strip down laptop to the motherboard. Bake the motherboard in a fan forced over at 80 degrees celcius for at least 24 hours (to get rid of any moisture that might be in the chip or solder). Immediatly after you take it out of the over, you need a hot air gun capable of reaching about 300 degrees. Heat the entire GPU chip and its board (don’t worry - all components can take 300 degress celcius for solder-reflow and did when the board was made). Keep bumping the GPU chip very slightly with a small screw driver, it will eventually become loose. Don’t lift it up however. Just keep the heat on for a few seconds to let the solder reflow and make a connection with the balls underneath.

After that let it cool down and plug everything back in and it *Might* work. If not can you heat it up and try again.

Jerkchick,

My Hp laptop has no sign of life except the LED ring around the power plug lights when plugged in. I totally stripped it and removed the mother board except for CPU, Graphics chip, RAM chips, power switch and power plug. Same results. If it were working properly, shouldn't I get some of the other LEDs to come on and maybe a fan, even in the stripped down condition?

My guess is either the motherboard is bad (although no sign of burns anywhere) ... or ... the power adapter is bad even though it registers 18.5 VDC.

Thanks for your help,

If it has a small flat cable connecting MB to the power switch, check if the cable is intact. I found mine on the dv6000 to have a break, so I was not able to power the lt on. Found a post abot the cable and got a replacement cable that works from digikey

Do you have a link to the post? I tested my power switch with a volt meter and it seems to be working. I also tried directly shorting the two pins where the switch cable connects to the motherboard and that didn't help .. but I'm not sure how it is supposed to work.

What notebook model is it any way. This is where I found info on the cable:

http://www.fixya.com/support/t638085-re_9269d

My dv6000 lost sound thru the internal speakers. The earphone jacks worked just fine so I started tracing the signal back from the speakers and found the break in the left cable running from the power switch board to the mother board. I tried to reseat that cable looking for bad connection. During this exercise I lost the ability to turn the laptop on with the power switch. I had the blue power light on at the power connector, but nothing else was happening.
I searched for the part number found on the cable and found the post at fixya. I delt with digikey before so it was easy to find the info on the cable. They sell them for 4.95 each PN HFF-12U-06-ND. Placed an order for 4 since I have another dv6000 and wanted to have spares just in case. In the mean time I needed to use the laptop. There is another cable with same configuration connecting mb to the touch switches on top. I used it instead of the bad one and was able to power the laptop on. Touch switches were not working but latop powered on and had sound. Once the cables arrived I replaced both cables and everything is up and running now.

Mc,
My laptop is a pavillion DV2715nr. Thanks for the suggestion of the cable. My power switch board has a 3 wire cable (not ribben cable) with 3 pin mini connector. But your symptoms during troubleshooting sound very simiilar to mine. I Tried just momentarily shorting the two switch-connected pins to see if that would substitute for the actual switch and that didn't help. -- wp

Then U may want to check with HP, some models have problems with motherboard itself.
My dv6000z stopped seeing the wireless adapter twice. The first time HP replaced the wireless adapter as well as motherboard. That was within the 1 year warranty. About 8 months later after installing SP3 (probably coincidence) the wireless stopped working again,. They replaced the motherboard again under warranty.
When I looked around for troubleshooting info I came across extended warranty from HP due to the problem with those motherboards. Yours might fall into that category as well. Check with HP.

Hey everyone, had the same problem, all i did was take out the battery, and unplug the laptop. the you hold down the power button for about 30-40 seconds, then put only the AC plug in and turn it on. worked for me.... might for you too.

Maybe your CD / DVD drawer is jammed. Try inserting a CD to reset the spring.

This has happened to my PC a couple of times, and it so annoying. the main problem is usually the motherboard, which may have overheated or shorted out. Also this can cause the power supply to also short out, sometimes in a spectacular fashion. lol

I have an HP Pavilion zd8000 which for many months now has only occasionally booted after 2 short & 1 long beep. I tried everything including send out for repair, but no joy until today. This may be a fluke, but it worked for me, so I thought I'd share. My laptop has booted successfully 6 times today.

Here is what worked for me: Right click on Local Area Connection/ Properties/ Connect Using: (mine is Realtek)/ Configure/ Advanced/ Enable: Optimal Performance, Enable: Speed: auto. I disabled everything else. On the Power Management Tab, Do NOT check: Allow this computer to turn off this device to save power.

My Realtek driver date is: 01/12/2009. I hope this works for at least some of you. Good Luck!

Hi you guys,

I see a number of you had problems with their laptop not booting up.
Before you spend $250-$400 on laptop motherboard etc repairs, do a couple of things with your laptop, such as leave it turned on for a while. I had the exact same problem and I resolved it finally today and I'm typing this from my laptop now. Read more about it here:
