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.

My Acer Aspire 5810tzg won't start, I've check the power cable and battery and they work fine on other machines, it just won't turn on


There is one thing you can attempt before seeking repairs. You should try a power reset.

1) Unplug the AC adapter
2) Remove the battery
3) Hold down the power button for 30 seconds and then release it
4) Insert battery
5) Plug in AC adapter and see if the laptop can power on

If it does not power on, you may need to seek support with Acer.

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.

Hi.

Take out the AC power jack and then remove the laptop battery. Plug AC power back in and see if the laptop will turn on. If it turns on let it boot the operating system and then shut down as normal, remove the power cord and reinsert the battery and again see if it will switch on. If it does then there has been a glitch with the battery. If it doesn't then there is a problem with the battery.

If the laptop won't switch on either with or without the battery then there is a possibility that the motherboard has developed a problem.


Good luck.

My laptop will not turn on even if i plug my charger in. what's wrong with it?


Hello,

If you cannot see any sign of power like blinking lights, then there are three possible reasons why your laptop is acting like that.

1. Battery
2. Motherboard
3. AC adapter

Enable for us to know what causes the problem, try the following troubleshooting steps:

1. Take a look the ac adapter whether the light is lit. If there is no light then it's the ac adapter that needs replacement.

2. If there is power in the AC adapter, then, unplug it from the computer. Remove the battery of the laptop. Plug in the AC adapter, and turn the computer on without the battery on it. If it does work, then the battery is not working fine and you need to replace it.

3. If you have tried the above troubleshooting with no go. It is now the time to touch the whole computer.

NOTE: Troubleshooting 1 and 2 can be done by any computer owner. A computer owner can also open up a laptop and try fixing it but I suggest that you bring your computer to a technician if 1 and 2 does not fix the problem.

Toshiba Satellite L300 shuts down when ac power plugged in


How about this step, try to turn off the laptop itself. Remove the cables and battery just like what you did before, then press and hold the power button for 10 seconds. Then, reinsert the cables and battery on the laptop and then turn on the computer itself. If the laptop restarts, shuts down or freezes with the AC power cables, two things that you should seriously consider. It might be the power cable itself, AC cable port or the circuitry going to the motherboard. And since you have cleaned out the fan and heat sink, you have isolated that problem. Have you plug-in another power cable on your laptop? If yes, then check if it works. Otherwise, the main issue is that the AC port is loose or the circuitry of AC adapter going to the motherboard is not not working. You can re-open the unit and check the circuitry from the AC port going to the motherboard. You may check the circuitry from AC port to the power supply if it is ok. If symptom persist, please contact your local dealer...

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.
