My hp compaq 6910p laptop not on adapter is ok **** i plug in laptop no power on no any light on


Unplug adapter using cheap multimeter, check for voltage on the Plug the goes to laptop.. the plug should be producing 13+ volts ( not sure exactly of Spec, but it is located on the power pack itself. )

Your problem sounds to me like your power supply is shorting out .

Alternative problem is the charge circuit on the mainboard may need to be serviced. ( commonly replacing mainboard- some facilites can repair )

Compaq Presario 2700US Notebook PC will not power up. Green power light is on


1. Take the battery out of the laptop & try to turn on the laptop using power adapter only. If the computer turns on, then the battery is defective & needs to be replaced.
2. Make sure the power adapter is not defective. Test the output voltage of the power adapter using a voltmeter. Compare the voltmeter reading to the nominal value written on the adapter or the laptop.
3. Make sure the DC jack is not loose or broken. A loose DC jack will need to be re-soldered. A broken one will need to be replaced.
4. If you have another processor which is compatible with your laptop's model, try swapping processors & test to see if the laptop will work.
5. The power button could be bad
.
6. The motherboard could be defective & needs to be replaced

Hp compaq 6720 laptop, wont charge battery, bought new battery have same problem. have tried several different chargers and they are all working, but not charging battery


If the notebook does not charge even after replacing it with new battery and checking with several chargers then it is laptop power jack issue.
You may need to replace it. However to confirm the issue is with power jack just remove the battery and try to power on the notebook only with AC adapter. If it does not then it is the power jack which is allowing the ac power to be charged.

If your notebook is in warranty then you can ship it to HP and if it is out of warranty then check the link below, you can purchase the power jack of the laptop from here.

HP Compaq 6735s battery light orange blinking


Have you tried another power cord? If you try another power cord, and it still does the same thing, then I think your laptop is having a power problem. You need to take is to a technician to fix the problem for you.

Best wishes.

Hi,My HP Compaq nc6000 just developed a problem of not coming on. I have checked the battery and its okay. I have blown its internal parts and it remained off. It only indicates the orange light for some...


try taking the battery out completely and see if the laptop runs of the main power from the outlet, if so then the battery may have a bad cell in it and would need to be replaced.

Primary Batteries
6-cell Lithium-Ion (4.4Ah) – standard
8-cell Lithium-Ion (4.4Ah) – optional

Power SupplyExternal 65 watt AC adapter

from looks of it the battery has gone bad
