Compaq Presario 900 power cord connection problem

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

Hello.

If you are not getting total power, the most common reasons are the power adapter/cord and power jack.

If you move/wiggle the power adapter at the point where it connects to the laptop, and the power goes off and on, the power jack is the problem.

The power jack is inside the laptop and either needs soldering or replacement.

If no change, the power adapter is probably faulty and needs replacement.

Hope this helps.

You can get a replacement power cord for this laptop from any elctronic or computer store near you like Besbuy or Radioshack, of you can order it online from this sites.

1. You possibly have a damage ac cord
or you have damaged connecting plug at the PC .
2. try to obtain a new AC cord.
3. Another possibility is the power supply for the PC needs replacement.
4. A PC technician can determine this for you.
Contact Compaq for repair rates because most likely this is a special power supplied system.

Maybe the power supply cable or the charging curcuit on mobo. Can you test the cord with a voltmeter or test light?

Is the power cord/brick *firmly* plugged in in all places? Sometimes, the cord from the brick comes out slightly, breaking the power connection. If your battery is old/no longer holding a charge, the machine wouldn't start again. Also, if above is ok, remove the battery, plug the power back in. Does machine start now? If it does - replace battery.

When you install a new battery and remove a battery always make sure the laptop is completely shut off and have the power cord removed so that you avoid any possible power surge.

Batteries generally don't last much longer than a year and I have found removing the power cord or battery when it is off to be a good practice.

Before you charge a battery make sure it is run most all the way down. Recharging a battery when it is not run down can give it a memory and you may only be able to charge it up to the point you started charging it.

Anyway, if the computer won't charge a new battery then you could have a bad motherboard. To be sure try another battery.

Check that your power adapter is working fine it may be that the power cable is broken somewhere between the adapter and the laptop. You could try another charger / adapter.

I think you sould check your batteru first.

• Remove your battery from lap.
• Add power card to lap.
• Make on without battery.
• If it works, then you need to replace the battery or you can chek your lap with another battery, if it fixe your problem. Then you should replace the battery.

Thanks and Good Luck
