Compaq Presario 900 power cord connection problem

I recently started noticing that my laptop's power cord was not making good contact with the notebook. I had to adjust the connecting piece is strange ways make contact so the computer would stay on. Then no contact could be made at all. I think this may be a problem with the connection inside the laptop itself. I tried taking the screws out of the bottom of the computer to disassemble it. However, I could not take the bottom off entirely. It seems there is something preventing it from opening all the way. Anyone have knowledge of how this thing comes apart?

Re: Compaq Presario 900 power cord connection problem

I've fixed a couple and finally resorted to using a cable retention device like the one in this video to stop the constant tugging and jerking that seems to cause the failures. PS the design of the pins/sockets is really shabby.

Re: Compaq Presario 900 power cord connection problem

If you do a Google search on your PC with the word "disassemble" or "repair instructions" you will likely get a hit. After you carefully get the motherboard out, the problem is typically bad solder joints on the dc port to motherboard. Make sure to use the least heat (that is, lowest wattage soldering iron) possible to remelt the solder. There are a few sites you can Google for "dc power port repair." If you are unable to do this many small firms advertise the service. Good luck

Re: Compaq Presario 900 power cord connection problem

As Pastorm stated it could be the socket, however, it could also be damage to the power plug that plugs into the laptop. My experience has been that I?ve had to replace far more damaged jacks by far then sockets. Usually what happens is that someone trips over the power cord and puts strain on the cable where it attaches to the jack. A quick test is to plug the DC jack into the laptop and while holding the jack still wiggle the cable where it attaches to the jack. If that doesn?t do it try holding the jack and wiggling it in the laptop socket. One or the other should cause a break in the power and you?ll know what to get fixed or replace.

It seems like the power jack on the laptop has to be resoldered to the motherboard. More than likely you will have to take the whole laptop apart to reach the bottom part of the motherboard and do de soldering work.

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



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

From your description there could be two different parts, one would be the power adapter that the AC power cord plus into, or the other would be the connector on the laptop where the DC power connects into.

You can buy either of these on ebay. Just search Compaq Presario 700. There are several power adapters and there are many parts machines that you can cannibalize the power connector.

I use a Compaq CQ60 laptop. Recently I noticed that when I plug in the power cable the charging indicator at the point won't come on. Yet touching the Earphone slot with the back of my hand indicated that...


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.

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.

Compaq Presario needed a new battery was installed labtop will not charge up!

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.

Compaq presario M2000 power cord won't charge my laptop

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.
