Laptop power shuts down after 2 seconds

I have a Compact Presario F700 laptop that just stopped working. When power is turned on, it shuts off after 2 seconds. Does not start any of BOOT process. Fan does not turn on. All 3 LED's on lower left hand side of keyboard area turn on, then 2 outside LED's turn off after 1 to 2 seconds. Also the LED on the touch pad mouse does the same. Trouble shooting done as of now:
1. Tried new AC Power supply/charger
2. Pulled battery out and ran from supply only
3. Pulled out hard drive and repeated 1 and 2
4. Pulled out RAM and repeated 1 and 2
5. Pulled out DVD drive and tried 1 and 2
6. Reseated Battery, HD, RAM and DVD drives, still same.

I am thinking that it may be the fan circuitry/sensor. I have tried to open it up but I can not find the tricks to get into it. I have removed all the screws I can find. Any ideas as to the problem?
Thanks,
Phil

Hold F2 key and set up to default settings choose to boot to the hard drive save it and exit.

if that does not work then hold F8 chose to log in safe mode and from there try to find what issue is causing that particular problem...

otherwise try to download the ultimate boot cd (click here) and burn it into a bootable cd inserted on your pc and repair whatever is causing your nightmare.

Compaq Presario F700 Won't Turn On


Assuming the unit is plugged in, this could be an issue with the power supply, or an issue where the cord connects to the laptop. If the power connector on the back of the laptop is secure / doesn't feel loose or damaged, you may want to simply get a replacement power supply from a local electronics store. Be sure to take the make and model information of the laptop and the power supply with you to the store.

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

Cant turn On my Compact presario f700


Assuming you have checked the the power strip or outlet by testing it with another electrical appliance to see if it is in operation, you can test
the power supply to the unit with a tester or oscilloscope. If it still does not work then check the cable that plugs directly into the unit and replace it if necessary. You can also open the unit to check if the cable is attached properly to the motherboard.
