Will not work with ac power adaptor but does with


Did you wiggle it a bit when plugged in? You can't tell from looking on the outside if the plug is fine because it goes bad inside where it is soldered. This is a very common problem, and have fixed many laptops with the same problem. All of them had a bad solder connection inside. Did you dtermine the plug was fine by plugging another ac adapter to your laptop or you just checked it visually? Hit me up I will solve this one for you.

COMPAQ V2000 WILL NOT POWER UP WITH DC/ADAPTER OR BATTERY


Hve u tried a differnt adaptor , the adaptor might be blown too ,try replacing the adaptor , also check for the power cord if it has any kinks in it which may be interrupting the power supply , since the adaptor 18.5 v 3.5 a is the most common of all hp adaptors u should find one to try .

I have a compaq presario V5204NR


Try starting it with just the adaptor or just the battery.
If the adaptor is broken it might not properly power-up, same goes for the battery. You'll need to exclude these two first.

If it starts with just the adaptor: dead battery.
If it starts with just the battery: defective adaptor (broken connections, insufficient power etc.)

In both cases you should probably call upon your warranty. That is, it that is still applicable.

If both situations don't work, let me know and we'll think further.

Greetings,

DarkNeogen.

Compaq Presario 1200 won't charge battery


dear N9YK

you can follow this

If you have a loose connection where you plug in the power on your laptop, or it works intermittently, you could have a bad dc jack. Symptoms
  • Move the power plug and the laptop loses connection
  • Broken or cracked dc jack
  • Laptop won't charge but worked on battery
  • Power LED and battery LED flicker when the adapter tip is moved
  • Battery won't charge
  • Sparks come out the back of the laptop
Why does this happen?
  • Flaw in manufacturer designs
  • Use of universal or non-original ac adapter
  • Lots of plugging and unplugging of the ac adapter
  • Tripping on or pulling the ac adapter cord
or you can check your dc amper in your adaptor

oke

Compaq Presario 1680 Notebook shows no power in window when plugged in.


Take the battery out disconnect the AC adaptor Press and hold the power button about 7 seconds. Put the battery in and connect to AC adaptor press and release the power button. If it caused by static-component lockup, issue will be resolved. If still there is no activity including no power light check the AC Adaptor if its working

Good Luck

Compaq Presario 700 won't power on


These are prone to broken power jacks that short out components on the mainboard. My shop saaw a lot of these come in dead like this and sometimes we could get them going again with a lot of mainboard work, but it seems they keep breaking.

I would save your money for another laptop considering the lousy reliability record these models have.
