thanks,

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?

That has been happening to me as well, i got so frustrated one night because it had been over a monmth since my laptop was able to boot, so i sorta hit the bottom of it, turned it on, nothing happened, just the stupid lights turning on. then i turned it off and decided to place my mouth directly on the vents leading to the harddrive and memory card and blew semihot air into it. i ddidnt think it would work and turned on the laptop again and was about to chuck it on the floor when all of a sudden i could hear the harddrive whirring and i was like "holy shit, it works!!!"

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.

Your laptop is probably overheating, which means the solders points on the graphic processor are damage by now. But it can be fix it is a long process

Ok i have a compaq laptop.

when i hit the power button.

The computer starts up (you can hear the hard drive and fan start) but then it shuts off right away.
then it starts again, then it shuts off. then again (like its going on, off on, off, on off.

does this for a long long time. never starts the windows or goes into the bio's.

I remove the bat, and power to stop it from doing this.

then i try again. same thing. so i do my steps over. try again. this time it worked.

now im on the laptop no prob even using it to type this message.

but i know as soon as i power down. it will take me a long time to get it to stop the (on off on off)

so what do i do in that case?

I'm having a similar problem with my hp pavilion laptop, its been going on for about a week now. 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! :-)

I to am having the same problem... first off if i let it loop for about 20 mins it will boot.. so i did a complete computer disassembly removing dust dirt grime anything and replaced the thermal paste and pads scraped the heat sink gunk off and clean all the parts with duster made sure all the connections were in place and tight.. and after about the whole 45 minute process after it was all put back together I tried booting and still the same problem so i called HP and they isolated it to the motherboard so I am going to buy one off ebay for about 140... unless your pretty amazing at circuitry and can isolate motherboard burns or anything like that I would suggest to buy a new motherboard off ebay hp charges 399 for the board thats not including service fees and all that

Okay i might have the same problems as you guys do, i press the power button on my laptop than the lights(no screen) comes on than 3 seconds later it shuts down.My laptop was still working on Wednesday night than when i came from from school Thursday afternoon i move the mouse a little, but the screen didn't come on just the lights(Power, Blue tooth, Wifi etc, little blinking lights by the corner of the laptop) than i noticed it was frozen i guess so i unplug my laptop power cord than took out(disconnected) the laptop battery so the system could turn off.Once i did that i plug in the cord than the Battery and press the power button on my laptop than the little blinking lights turn on for few seconds than turns off..

Please help me~!! give me any suggestions.

P.S: I've tried disconnecting the power outlet and battery several times in and out, i've tried everything you could do without going to Bestbuy and getting it fixed.Also i have several times disconnected my power outlet and battery fron the cpu/laptop whenever it frozen.It doesn't have Virus(might have) just games stored on it


[Note]
My cpu is a Dell Inspiron 1721 Home Premium Window Vista(almost 1 year old).

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..

for all who having problems with labtop automatically just shutting off a key problem could be the fact that its overheating when your labtop gets too hot the sensor in the labtop tells it to shot down and when it reaches a cooler tempature the labtop will be able to turn on again. I first noticed this whenever i have my labtop on the bed because of it being on the bed it stop the hot air from being able to leave the labtop making it hot but when its on let say a desk its able to release the air if you want to use ur labtop on ur bed or anywhere besides a desk you might want to use a cooling pad that has fans this enables the labtop to stay cool without overheating thus keeping your labtop on it can cost around 10 -20 bucks hope this helped

I have the same problem with my hp dv6000. I take the battery out and put the laptop the freezer for about 5 minutes and it usually starts after that. I also checked the memory, HDD and software, no problems. Guess it's the motherboard. Now I just leaving it running 24/7. Next time I'll buy a Dell or Acer...

its a hp pavilion 1x 1000
the screen wont turn on....all the light are on but there's no image on the screen..the light wont turn off...help plz

I have a hp and the same exact thing happened to me and I have2 take the battery out put it back in and hit the power button and after a few times it starts up goodluck

Well i have had the same problem. At first i thought that the cause of this was that I play on my laptop too much, but when I went to best buy, to have it checked, they said that the mother board was overheated. They replaced my laptop with a new one.

This might help

I too have the same problem as a lot of you. My HP laptop is only a year and a half old. My next laptop (or any other computer) purchase will definetely NOT be an HP.

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. =)
