SOURCE: HP Pavilion dv4000 battery won't charge

all you really need to do to find out if it might be broken is to check and see if that DC Jack on the computer is "wiggling" around, if the center part is moving around. If it is, then there is a chance that it is broken. I used to work at a computer store where the owner would resolder new DC power Jacks into laptops, but he was the only one in town who did that. So you might want to check around at the local computer repair or electronics stores to see if someone does that type of thing. Also, have the power supply checked out, it could just be dead.

It sounds like you have a faulty power jack, and possibly a dead battery as well. You should take it to a person you may know that can order and solder a new one in or take it to your local electronics repair shop. I do repairs like this on a daily basis for my computer business.

The adapter stopped charging my laptop due to a faulty wire, I bought a new adapter and now as soon as I plug in it starts for a second and turns back off. The charging light blink and it doesn't


When you connect the power adapter into the laptop, does the power LED light up? If not then - The battery adapter or the adapter's power lead or the laptop's power socket could be faulty. Check power adapter's DC plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard. This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. If you cannot DIY then I suggest you get a quote first.

Hp compaq 7620s wont start ( constant blinking blue light )


The adapter output appears correct, the batteries often work in that voltage range. But the problem you have is the motherboard, the HP line has constant trouble with the main board, only option is board replacement.

Your motherboard is probably shorting out your A/C adapter, you may need a new motherboard. With a Dell, the A/C adapter light will be green when plugged into the wall but as soon as you plug it into the PC the green light goes off. Which means that the Motherboard is shorting out the A/C adapter...

Dose not turn on


Try to remove the battery some laptops will not power up if the battery is dead.
Another thing is check to make sure that your adapter is working and you see a green light.

Compaq C502US Laptop Won't Boot LEDs flash


turn it off, pull the battery from the bottom, and try it again... chances are, the power adapter is not rated properly for the notebook, or the battery is dead and won't hold a charge anymore, in which case, recycle the battery.
