replace the bios chip.

Not sure of your particular MB, but most always the switch is a pair of pins in an array where the front panel LEDs and reset and power switch are.
This array of pins is almost always at the lower right hand side of MB. Assume the components side is facing you and the expansion slots are at your left hand, (where you add extra cards like video etc). then look at the lower right side or bottom edge, mostly right at the edge of the board. Should be an a double row of pins, at least 8 maybe up to 12. Look real close next to these and you may see print indicating which pair do what. PS = power switch. RS = reset, HD = Hard drive LED PLED = power led light.Spk internal beep speaker etc. (Note LEDs require correct polarity to work) Sometimes no print there.. Then you need the manual to decipher pin pairs. Or experiment. All you need to do is make the connection momentarily (like push button) with a small screw driver tip to start it, while looking for correct pins.
If no power on check your power supply connections on the MB. Or suspect either MB or Power supply issue.

What is the exact model number for your laptop?

Sounds like the infamous nforce chipset problem. If still under warranty take it to place of purchase & RMA it. If not & you're technically inclined, you can try the bake method to revive it or take it to a tech

Get a new motherboard, this one is dead.

Compaq (... | Answered on Oct 14, 2010

It depends on whats wrong with it, What was it doing?

Also with the cost of motherboards these day's do you think it's financially beneficial to fix yours or buy another?

motherboard instruction are given in the manual provided with the motherboard at the time of purchase or u can download user guide from net.

Please logon to the website http://www.compaq.com and select the product then download the user's manual. Such information’s are usually given in the user’s manual. Although Compaq is presently owned by HP, but user support is still there. Let us know if you were looking for something else.
Thank You

As for the Power Supply 99% sure it is an ATX which as long as you get the same Watt as the existing you will be okay. Make sure you look at your existing connectors to see if you have a 24 pin or 20pin motherboard and 4 pin or 8 pin additional power plug (black and yellow wires) and the new power supply has matching connectors....older ATX supplies have only 20 pins, but there are converters from 20 to 24 pin available.

Watch for the new power supplies and your drive connectors as some of the new power supplies have limited ATA plugs...if you have a lot of ATA devices you might need SATA power convertor plugs or ATA splitters to get all you ATA devices up.

The truth is that I cannot give, not even an idea of how to set the jumpers. The way that the manifacturer gives orders to his employees is a well kept secret. The way that the jumpers are set is to give a very precise voltage to the CPU chip. Tha danger that everybody is worried about is that a vey small rise in the voltage, for instance going from 1.8 to 1.9 volts, may cause that much of an increase in the current through the chip that the temperature may increaseenough to destroy the chip. The voltage for the CPU chip is adjusted for a pre-set frequency and at that frequency the heat generated in the CPU chip is calculated to be dissipated through the heat sink, which may even have a blower. Increasing the frequency of a CPU than what the manufacturer intended is called "overclocking" and up until now it has the hobby of some amateurs, who experimented and actually have had good results. But look at the sequence: the voltage on the CPU is raised slowly, watching the temperature of the chip, not to exceed the point of no return. Once the heat sink is unable to maintain the safe temp., the system is dismantled and a new heat sink perhaps with a more efficient blower, will place the chip within its thermal limits. If your CPU has not burned out already ask the manufacturer of the mother board for information and get figures that will help you to increase the frequency and still, up to a point, avoid the destruction of the chip. As a point of information Compaq never has manufactured any mother boards. They specify them to their favorite supplier and he delivers the quantity they need. The same holds true with the mother company HP. Tell me if you are out of business with your computer and I can do an inquiry and there is the chance that we get some onfirmation. One alternative, not very cheap, is to buy a MB that has a provision for gaming and has adjustments and control of the heat dissipated by the CPU chip. I desire to help all I can that we can have your computer running, under the limitations said above.
We tahnk you very much for considering our service...

What model does this MB belong to? If it is a newerMB the only jumper settings you should see would be the clear BIOS jumper. Alot of the newer motherboard settings are done thru the BIOS.


try looking here

good luck

1. Memory is upgradeable to 3 gb's total
2.You can use any AGP video card including any (Nvidia AGP video card)

Hope this answers your two questions, please leave positive feedback if it does.

Try removing the memory one by one try that first if that does not resolve then It would be your motherboard.

thank you from Fixya
