Compaq Presario F700 keeps turning on and off

Recently, every time I turn my laptop on it turns off after a few seconds, then turns itself on and repeats the process until I turn it off myself. It's a compaq presario F700, and I'm guess this is some sort of over-heating problem. I'm not able to run a virus scan or anything like that because the computer doesn't even load and the screen doesn't even light up before it shuts itself off, but I'm pretty sure it's not a virus. I'm thinking I need to clean out the fan or something, but I'm not quite sure how to access it (I don't want to unintentionally do more damage). Anyone else had this problem? Ideas on fixing it?

    Alright, so I took the computer apart, dusted the parts and everything (nothing looked totally damaged from what I could tell), put it back together (apart from the screen becaue I also use an external monitor), but nothing's changed. I'm not familar with scopes, what do you suggest?

At this point I assume you've tried to go into SAFE mode, and into BIOS with no luck. You're right about the overheating but I think the damage is done. If the unit will no longer stay on in any mode or condition then heat has ruined something. First easiest part to check is memory. The check the CPU (most laptops still have a plug in CPU). If neither of these are suspect then take everything off the motherboard, including the screen (I use and external monitor). If the problem still exists then it's time to use a scope.

    I have to assume you tried replacement memory? When you took everything off the motherboard (hard drive, optical drive, screen. PCMCIA and other ports did you try turning it on? As I said before a scope is now needed to see what's happening to the reset signal the CPU gets. If you're not familiar with one then you'll need to bring it to a reputable shop.

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

Compaq Presario F700 Laptop power up issue


Remove your cpu/gpu heatsink, apply a ermal bonding, this will prevent shut off because of cpu/gpu overheating(chipset detects temperature faulty in the firsts seconds of operating your laptop), if this didnt resolve your problem, naybe and issue with your Mobo.
