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

    Hey , thanx 4 writing back. Now if there are no lights at all after removing and reseating the memory and HDD then it indicates that the motherboard has itself has an issue. In this situation you need to check motherbaord closely to check if the cmponents on the motherbaord might got damaged and not allowing to complete the boot order. If your laptop is under warranty then you can send to manufacturer and get it replaced. Thanks

I have an Advent 6651 Laptop and it wont power up all the lights come on (both power lights and the Webcam light) the screen doesnt turn on and the cooling fan doesn't spin.... I have tried removing he RAM...

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.

I have an Advent 9117 which I have to remove the power lead from and un-plug the battery, then JUST re-plug the battery in to get it to start. ANY ideas?

This can happen if the power adapter is failing. Try using a different power adapter and see if the problem is still there.

Screen does not turn on but green light is on.

Green light indicates the monitor is getting power. Nothing coming up on the screen indicates, No Signal.

No signal from the computer. This means the computer itself isn't working.

A bad power supply in the computer can cause this. A bad power supply is the leading cause of desktop computer failure. It is replaceable, and can be done by the owner relatively easy.

You may have a computer tower that the Power light comes on, you hear fan/s spinning, (Including the Power Supply fan), and it sounds like the harddrive is running.

ALL the lights in your computer use less than 1 Watt.
EACH fan uses 2 to 3 Watts.
A harddrive sitting there spinning in an endless loop, consumes about 2 to 3 Watts.

A Processor uses 51 to 125 Watts. Depends on what Processor it is.

A weak Power Supply will have enough power for lights, fans, and that harddrive sitting there spinning.
It won't have enough power to turn on the Processor.

[No processor operating, then the harddrive sits there spinning in an endless loop, because there is no processor to find the boot sector]

For a test, connect your monitor to a know good computer. See if it works.
Now connect that other monitor to your computer.

Mother board no display

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.
