Hello,
I have a HP pavilion dv2000 laptop. My problem with this laptop is, that one day I turned it off by sending it to hibernation and the next day I turned it on it wouldn't start at all. The only response I get is 1 short 1 long and 2 short beeps. After that it's just 1 long and 2 short beeps. Only the power led is blinking and the led of the touchpad which changes from blue to orange.
I tried to take out every part of the laptop: battery, keyboard, memory modules, hdd but itt didn't solve my problem.
After that i disconnected the cord of the small battery and voil la the laptop starts up, but gets stuck at a screen telling me to set the bios dates correctly and press f1 to continue. At this point the keyboard of the laptop doesn't respond at all. Using an usb external keyboard I can continue the boot process, but if Vista starts to load, it loads for a while from the hdd but after a few secounds it gets compleatly stuck, and only pulling the plug helps me.
The only thing I can load on this thing is a linux live distro.

I have to keep the cord of the small battery always disconnected, otherwise the system only starts with the above mentioned beeps.
Another note: I run the test of the bios for the memory and for the HDD, the memory passes, but the HDD fails at the deeper test at 20%, and the same happens with a different HDD as well. From linux the hdd is accessible without any problems.

So if anybody has a solution or an idea...
By the way: Hp send us away saying sorry you are out of the waranty. Laptop is 1 year and 20 something days old...
