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
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
Replaced power supply 2 times, when I plug it in it starts to turn on then just shuts off wont stay on or charge..
does it stay on when plugged to ac power
Make and model, and can I get more detail into what is going on?
