Hello,

In that case it was proven that the power input to the laptop got an error, however try remove the battery and power it by the laptop adapter and switch on. if the system boot, the battery need to be replaced, but if does not power on, you have to check the power input of the laptop, maybe the fuse in it blown out. You can let the vendor do it for you, or bring it to the service center if you can hardly do the job in fixing it.

that problem require a series of testing. so if you need more information notify me for further solution. melnavz

Instructions

1
Determine if the laptop battery is defective. While less than 1 percent of batteries are defective, the possibility is still there. If the battery is new and only charges some of the way, it may just require a BIOS update to charge fully. New batteries that refuse to charge at all may be defective. Purchase a new laptop battery to replace the defective one.

2
Test the laptop power adapter to see if it's faulty. Run the laptop directly from the laptop power adapter and without the battery. If the laptop does not work with the adapter plugged in, the adapter is dead and you will need to replace it. The laptop battery may refuse to charge if the adapter is faulty. Charge the battery with the laptop turned off.

3
Insert the laptop battery into another laptop to test it. If the laptop battery charges in another laptop, the laptop's motherboard may be bad. Replacing a motherboard in a computer can be very expensive. If the cost to fix the computer is not worth the cost of replacing the motherboard, consider purchasing a new laptop.

4
Reinstall the battery to ensure all connectors latch properly. The latch mechanism that holds the laptop battery should click into place. If the latch does not close, remove the battery and examine the compartment for signs of damage.

5
Troubleshoot the BIOS to determine if there is a hardware problem. Turn on the laptop and immediately enter BIOS setup by holding down the "Del" and "F1" or "F2" keys, depending on the make and model of the laptop. When the BIOS screen appears, see how long it takes for the battery to charge down. If the battery does not last as long as the BIOS setup, a hardware failure may be the problem.

My laptop wont turn on or charge i bought a new charger and it still wont work how can i fix it?


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.

Compal RM CY25 Laptop. new battery won't charge.


Unfortunately, the charger socket in the motherboard does not drive electricity to the battery to get re-charge it. It is a typically motherboard problem(Do not confused with a power jack problem). I can not be repaired it.
Two options work always hook with power adapter or get ride of her.

Laptop died suddenly and is not charging


Take the battery out and discharge the capacitors by holding down the power button for 15 seconds. plug in the charger without the battery in to see if you get a charge light. If you do, replace battery and plug in charger and power on laptop. If this does not work, you may have to pull the cmos battery for 15 minutes and try it again.

possible cause.... check to see if there is a voltage on the connector of the power connector to the laptop.

try disconnecting the battery from the laptop, and connect the power connector, if the laptop works then you know there is a problem with the charging circuits or the battery itself.

Acer aspire 4920 charging mechanism failed


Most laptops, as in 99%, have one board and everything is on it. They don't really have a power supply since the AC adpater provides DC voltage already. There is just a voltage divider that take the incomming voltage and changes it to the various voltages the machine needs. The charging mechanism is also on the mainboard. I've very seldom seen a seperate power or charging board in a laptop. Unfortunately since you've already replaced the battery and the ac adapter and since the adapter is powering the laptop then there is definitely a problem with the charging circuitry on the mainboard. This isn't something one can repair unless you start changing micro components and ICs on the board which isn't recommended. Looks like a new mainboard or a new laptop is in your future if you want it to run off battery.

Another option is to get an external battery that mimics your ac adapter but that wouldn't give you a very long run time compared to the internal battery.

Don't forget to rate my solution in your premium thread as FixYa if you think I helped solve your problem. Thanks.

Your battery is not charging anymore the capacitor inside of it is weak or leaky that's why they cannot hold the voltage charge you need to replaced it.
