Presario F700 Laptop.. Wont boot up, turns on and then off... that's it

Ram was your best bet on a laptop. But you can load XP onto itself so it reloads without deleting any files. However, if it still may fail. If that happens a clean install is your next step.

it seems that the smps of th system has gone faulty....

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

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

First - re-seat the harddisk and reboot the computer. If the computer does not boot up then reboot andgo into the BIOS configuration to see if the BIOS detects the hard drive. If itdoesn't detect the hard drive then it could be faulty.Then the hard drive needsto be replaced in the computer/laptop, Windows installed and the computer orlaptop's device drivers plus your programs etc. to get a functioningcomputer/laptop again.

I've gist had the same problem after flashing bios ...
go to BIOS and change the SATA mode to IDE. it worked for me.
original instructions:
also You have to turn OFF (disable) the boot from network. The error your seeing is result of the network boot rom not finding PXE server to boot from. Again, be sure to disable boot from network.
PLUS it seems if only 128 MB is showing as memory then the memory sticks might be damaged and not able to retain information/data to complete the installation process. Best take them out clean it properly & replace & try again. Nothing to do with BIOS!

Go to HP Support & Drivers.

If the laptop appear to boot up (ie the hard disk LED flashes) but you cannot see an image on the screen, then you could have a backlight problem.
To determine the actual fault, please follow my instructions which are on this link :-

Hello there
Hints:
1) You got a driver or device problem,
2) use the drivers that cam with your f700 particulary these ones, 1) video card 2) sound card (sometimes if driver is bad, it can cause these problems)
3) RAM problems, to isolate the problem, if you have the expertise take ount one ram module at a time and turn on the computer. see if these helps!

is there not a jumper on the motherboard to reset bios? you could also try to remove the bios battery (a watch-type battery located directly on the motherboard)

you can flash bios most commonly by downloading the bios update to a floppy, and then booting with the floppy in the drive, but if you do it wrong, the end result will be a very expensive paperweight, hence flashing bios should be a last resort...
