    will it on if using new charge battery? if yes, then something is wrong along the dc input line of your laptop. a broken inductor that cuts the supply to go into your system. you can replace it with any wire serve as jumper then solder with no problem. your problem may be lies on how to dismantle the laptop and look for this small inductor. you may able to find it by focusing on the line in of your dc power supply. somewhere along this is cut. you need to have a multimeter to find it. let us know.

If there are no apparent physical defects on the laptop, power cord, or battery and the laptop is not receiving any power even when plugged in then either your power cord or some circuitry in your laptop have become damaged. If your laptop is still under warranty sending it off to HP for repair will be your cheapest solution, otherwise you may try replacing the power adapter.

HP Elitebook 2530 Pindicator says battery charging but battery not charging

Could be a back power brick or DC jack yes. Power off the computer and remove the battery. With the battery out plug in just the power brick and turn on the computer. If the computer doesn't power on gently wiggle the plug into the laptop and repeatedly hit the power button if it comes on briefly then off again you dc jack is loose. If it doesn't come on at all then its the power brick. If the laptop comes on gently wiggle the plug into the PC. Powers off while wiggling DC jack.

Monitor turns black

As you had stated that the monitor is working if the power brick is off.The back light shutdown might be a cause of static from your power brick, or other thing is it might be your setting for back light level or power scheme.Some configuration needs to open BIOS settings.To check if the power brick is the cause of problem is good to have a known good one or try to monitor if it is charging or not by monitoring the battery indicator if the power brick is off.

Have you tried a new power brick or tested the original?? it should measure around 19 volts and you should be able to draw at least 3 amps from it.
(Be aware that if you have a short circuit in the computer it could destroy another brick connected to it).

"battery doesn t charge how do I know if the power cord or the battery is bad on my Presario M2000

If the battery is over a year old then it could be dead.Anything over two years I would bet on it. Usually the power bricks are very reliable. To check it you just need to put a power meter on it and check the voltage against what is printed on the brick. It should be slightly higher.

Without a meter it is pretty hard to check. You should get some indication that it is plugged in. It may have a power light on the brick or the laptop that shows it on even if it wont charge.

it might be that the AC adapter is no more working. To confim this, remove the laptop battery and test the AC adapter with the laptop.

You can also borrow a friend's AC adapter and test it with your laptop.

I wish you good luck.

Laptop compaq presario v2000 is not charging the battery. It is functioning well on external power supply. The battery has been replaced with new barttery but it is not showing the charging status but...

This is probably either a bad power supply brick or a bad system board. Try to borrow a power brick from somebody else to see if this fixes the problem so you can isolate it as this is a much less expensive problem to fix.

If you have a travel charger, be sure to press the button on top to put it in charge mode.

Laptop not powering

try a simple power cycle. Take out the battery, leave power adapter plugged in. Hold down the power button for about one minute. Then hit the power button normally this should correct the problem
