My compaq is power on for 2 second and off , how to fix is thank you


You need to print this out-on someone else's computer. Hope it works for you!
Remove the battery and charger/ac adapter/power cord from your Compaq Presario F700 laptop, press and hold the power button for 20 seconds to discharge any residual current inside the Compaq Presario F700 . This clears your RAM and is like a hardware reset. Replace the battery and charger/ac adapter/power cord and turn your Compaq Presario F700 laptop on.

Boot in "safe mode". As it starts up press F8, the computer ask you if you'd like to start in safe mode. Highlight "safe mode" and press enter. See if your laptop is booting up ok .

If your Compaq Presario F700 boots ok, do the following,

Try System Restore first,
Start Menu->All Programs->Accessories->System Tools->System Restore. Choose the most recent date before you the encountered problem. If it doesn't work, try the next date.

If System Restore does not fix it, as a last resort, you might need to fdisk, reformat your laptop hard disk clean and reinstall OS, that usually fixes all bugs. Before going that route, try following,

Uninstall unnecessary programs and applications.

Scan with a antivirus program

Scan with a spyware/malware program

DEFRAG C:

CHKDSK C:

Clean up and repair registry problems with registry repair software of your choice

If the problem persists, did you check if it could be your Compaq Presario F700 laptop power cord or power source problem? Defective or insufficient power supply might cause error messages that are misleading. Take the battery out and power on your laptop with the charger only. Make sure your Compaq Presario F700 power jack and charger plug tip are securely connected. Did you notice the power jack loose? You can find laptop power jack on ebay. Fixing and soldering the power jack requires professional skill though. The charger green/blue LED should be on. If not, replace the defective charger. Compaq Presario F700 laptop battery charger, especially its power cord/cable, lifespan is limited and does not last forever, consider buying a lifetime warranty charger online from company like www.topmic.com

CAN I USE A DIFFERENT ADAPTER TO CHARGE MY LAPTOP


There are aftermarket adapters that can be purchased cheaper than the ones provided from the manufacturer. Unfortunately, there is no standard for notebook charging adapters. This means there are many different adapters available, with differing plug sizes, voltages, and current ratings. Having lost your adapter makes this a problem, as you cannot get the information from the adapter. Go to the manufacturers website and see if you can find the specifications for the adapter. Output voltage, current, and plug polarity are the three important items to verify. You can use another adapter if the voltage and polarity match. The current rating is less critical, but should not vary from the manufacturer's specification by more than +/- 10%. Too little current rating will overheat the charger, too high may cause the battery to take charge too quickly and it could overheat.

Sounds like the power converter. The power input and the battery are single voltage. The computer requires multiple voltages which are generated by a power converter. If you have installed this motherboard, ensure the connections to the power converter are correct.
