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

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

I have a Compaq Presario F500 When I press the power button all the lights light up for a few seconds then it shuts back off


remove the battery then try to plug the charger directly on your laptop without a battery.. to test if the battery is working properly. if not.. maybe your main board have a problem. just like athe compaq presario of my friend. also mainboard problem.

I would assume that your hard drive is spinning? If not your system will not boot because of a faulty or missing harddrive. Last known good config only works on the operating system and would not work during POST. Can you give a little more information please?

Compaq presario 2500 notebook won't boot


This sounds like a weird solution, but it worked for me. I recently bought a used Presario 2500, it worked when the guy showed it to me, when I got home it didn't work two days later. I tried several tips from the web, finally I started pushing several buttons randomly. I pushed the Email (Envelope) button, and the computer powered on suddenly. Now, the Envelope button is the only button that will power the computer on. When the computer is on, that button will also bring up Outlook, but when the computer is off, that button turns it on. Let me know if this fixes it for you.

Compaq Presario R4000 Notebook won't boot


Seem to be a problem with your power switch doing malfunction or bad motherboard connector or your computer has been setting at hibernate mode. Check those settings going to >> Start >> Control Panel >> Power Options..........Set your droplist to "never: and also UNCHECK the hibernate mode.

Another tip, take out the battery, and see what happen (only connected with AC)

Dead laptop


Check the ac adapter is the proper one for that laptop. Check the power jack is not damaged or loose. let laptop site without battery or power for a few hours. remove battery and retry power. try another ac adapter if that doesn't work, you may have a reset button but not likely to solve the problem. sounds like motherboard is damaged, or something blew.
