I replaced the ac adapter on the motherboard of the Gateway NV5207u and now when I try to power it on, won't power on. battery light red


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.

Mini dell 910, no power


Here below are possible causes and troubleshooting steps of laptop that can't power on, hope it may help:
Possible causes:

1. AC adapter failure.
2. Power jack failure.
3. Motherboard failure.

Possible troubleshooting steps and repair solutions:
1. Test the AC adapter with a digital multimeter. It's possible that you have a failed AC adapter. If you don't have a multimeter, test your laptop with another known good AC adapter.

2.It's possible that power jack (socket where you plug the AC adapter) is broken. Remove the motherboard and take a closer look at the power jack. In some cases you can fix the jack by resoldering it on the motherboard. In other cases you have to replace the jack with a new one. Using a multimeter, test if the power goes to the motherboard through the jack.

3. If replacing the AC power adapter and jack on the motherboard doesn't help, most likely you have a bad motherboard. Replace the motherboard.

No power


Hello, If the battery won't charge and the laptop won't turn on but the ac adapter works with other laptops, then the problem is the port where you plugin the ac adapter. Some of the laptops has it built in to the motherboard. So you might need to have it repaired by a technician. Or if the laptop is still in warranty, you might need to send it to the manufacturer to have it repaired or replaced. But if the laptop works without the battery, or it will turn on but the battery indicator is not lighting up, you're facing one of these problems. 1. The battery itself is dead. 2. the battery bay is loose 3. the battery itself is loose Hope this helps

Dell Inspiron 1521 battery not charging


Laptop batteries power a laptop when it is not connected to an electrical outlet. If the laptop battery fails to charge when the laptop is plugged into an electrical outlet, the battery is likely dead and needs to be replaced. Unfortunately there is no way to fix a dead battery. However, while a dead battery is the likely cause, it is not the only cause. The AC adapter may be broken, in which case the battery won't charge, or the battery contacts may be dirty and need cleaning. Prior to replacing the battery, perform simple tasks to ensure a dead battery is the cause of the problems.

1.Power down the laptop. Gently pull the AC adapter from the side of the laptop for removal.

2.Place the laptop in front of you, bottom side up. Locate the battery release mechanism. This can be a button that slides or needs to be pushed to unlock or release the laptop battery from the housing unit. Press or slide the mechanism. Slide or lift the battery from the battery bay for removal.

3.Insert the AC adapter into the side of the laptop. Power on the laptop. If the laptop does not power on, ensure the AC adapter is securely plugged into a working electrical outlet. If the electrical outlet is working and the laptop won't power on, the AC adapter is not properly working and needs to be replaced. Remove the AC adapter.

4.Dip a cotton swab in a small amount of rubbing alcohol. The cotton swab should be damp, not dripping wet. Lightly rub the dampened cotton swab onto the battery contacts and battery bay contacts to remove dust, buildup and grime. Allow the contacts to air dry.

5.Align the battery over the battery bay. Either press or slide into place. A clicking or snapping noise produced from the locking mechanism will confirm the laptop battery is securely locked into place.

6.Install the AC adapter. Allow the AC adapter to fully charge the battery for 8 hours.

7.Remove the AC adapter. Power on the laptop. If the laptop does not power on, the battery needs to be replaced.

The toshiba laptop a505 S6980 will not charge the battery when the AC is plugged in and dies immediately if unplugged . Meters shows 0% available (plugged in), charging. But it is not really charging.


Ifthe laptop battery is more than 3 - 4 years old then the battery could be wornout. Rechargeable batteries have a finite number of charge and discharge cyclesand will lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up atall. ORThe battery shows a 100% charge but when the adapter is disconnected thebattery drops off to zero capacity in a very short time. Ifthe battery drops to an unacceptable charge level then the battery needs to bereplaced.

Shut off and won't come back. It's like it is dead.


follow this procedure:
1. unplug the ac adapter and keep it unplugged.
2. Remove the battery and keep the battery unplugged.
3. Hold the power button down for 15-20 seconds(Nothing will appear on the display and none of the lights will light up)
4. Release the power button and plug in the ac adapter ONLY. (A power indicator light should be lit on the ac adapter when it is plugged in)
5. Normally power on the notebook.
6. If the unit does not power on, remove the ac adapter and insert the battery into the system.
7. Plug the ac adapter back into the system, the battery charging indicator light will light up. If the battery indicator light does not light up, the ac adapter may not be providing proper power to the unit, and may need to be replaced.

Toshiba Tecra M2 Series


Was the laptop on when it turned off? It may be a PSU problem but we can determine this by removing the battery. Make sure you disconnect the AC adapter while your removing the battery. Inspect the contacts and make sure`there are no black marks or any other dirt. Leave the battery out and plug in your AC adapter. Try the power again. 
There are a couple of possibilities in terms of problems that I can suspect so far. Did anything out of the ordinary happen when the computer just stopped working all of the sudden.
1. Battery has failed and short circuited the contacts 2. Power supply failure 3. Motherboard could have failed in style. 4. Power contacts for the AC adapter are damaged.
