Model: HP Pavilion Dv6000 (Or Dv6700, depending which sticker I believe)
CPU: AMD Turion 64
OS: Windows XP (don't know which edition, can't boot that far)
A family member asked me to try and fix this computer after it suddenly refused to boot. She says that it was fine one day, and that she hadn't installed any software or done anything out of the ordinary (like open the case), and when she went to use it the next day it wouldn't boot all the way. Instead, it would power up for a couple seconds, then shuts off, then power up again and repeat this cycle until the battery is removed. This was the state it was in when I received it. I searched online for people with similar problems, and found suggestions such as re-seating the RAM and checking if the power button is stuck. I tried both of those, with no change in behavior.
The next suggestion was to reset the BIOS by removing the CMOS battery. I'd have CMOS batteries go bad in the past, and my experience was that the BIOS would pull default settings from a ROM chip and continue to boot with those. So I removed the CMOS battery and waited 30minutes. I plugged the battery back in and pushed the power button. The computer powered up, but the screen remains black. Also, I can hear it do something with the CD tray about once every 10 seconds. I tried to power up with an XP install CD in the tray, just to see what would happen, but it does the same thing. Pressing ESC, F1, F2, F8, F10, F11, or DEL after the power button, does nothing.
Edit: I just tried what I'm told is called a "hard reset". I removed the battery and held down the power button for 60 seconds. Then I connected the AC adapter and pressed the power button. Now I'm back to the power on/off loop it was doing when I first got it. Well, at least when I give it back it won't be worse than when I got it :/
This is where I'm at now; the computer is completely unresponsive. I'm afraid I've destroyed my relative's laptop, and I have no clue where to go from here. Thanks in advance for any help you can offer.
