Re: power light comes on but not working
First you need to determine how many blinks you are getting when you try to power on the laptop. Check the blinking codes below and reason behind that for HP Compaq laptops Blinking battery power LED Battery Insufficient charge on the battery Blink: 1 - Caps Lock/Num Lock - CPU CPU not functional Blink: 2 - Caps Lock/Num Lock - BIOS BIOS corruption failure Blink: 3 - Caps Lock/Num Lock - Memory Module error not functional Blink: 4 - Caps Lock/Num Lock - Graphics Graphics controller not functional Blink: 5 - Caps Lock/Num Lock - System board General system board failure Blink: 6 - Caps Lock/Num Lock - BIOS BIOS authentication failure You need to first Remove the memory module (RAM)- Try to power on the laptop ? then again reset it and try to power on. Check whether it is coming on or not. try the same procedure with Hard drive. If laptop is getting power on after removing one of the device then we can be sure that that particular device is faulty and we can change that then? Let me know if you find any difficulties doing this.. I hope this will help you to get it work. Plz vote for me..Dreamkam

This is a pretty common problem with this model laptop, sadly. It sounds like you've done some reading on it.
Have you tried removing the BIOS battery, waiting 1 minute, booting up without it in place, then replacing the BIOS battery?
Next best thing is to talk to Advent's tech support and try to get them to repair it since it appears to be faulty cooling. If you are within warranty you'll have a shot.

well it looks like you had a phisical problem with the harddrive that made the data to be unreadable the only thing you can do is to try to reinstalll the operating sistem and if it doesent work try to replace the harddrive
take the bottom cover off and take out the cmos battery, i had the same problem turned out to be a power problem, check that all the cables for the screen are inserted, an maybe try it on an external monitor, if stil no output chances are its the motherboard,
Looks like the lights are on? Fans spin? Sounds like the harddrives spinning? The power supply is bad. has just enough power to light lights, and spin fans, but not enough for the processor. (No beep sounds, because BIOS hasn't done a memory count. It's not going to)
ALL the lights use less than 1 Watt. EACH fan uses 2 to 3 Watts. The harddrive just sitting there spinning, uses about 5 watts.
Processors use 55 Watts to 125 Watts. Depends on the processor. Not enough power to turn the processor on, the computer won't work. Computer isn't working there isn't anything to turn the monitor on. No Signal.
