Laptop won't charge

The first time it did this I thought the battery and/or the AC Adapter were bad so I replaced those. But when I have the laptop hooked up to charge, nothing is happening. The problem is not with the battery or AC Adapter but with the computer itself. Any suggestions?

The sucky thing with laptops is the electric plugs directly into the motherboard. then the electricity goes from the motherboard to the battery, so i'd have to say the motherboard is bad you could get a new one, but it costs alot of $. So I suggest bring it to your local computer shop and see what they can do.

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

AC Adapter issues Q & A.


Laptop switching to battery while connected to AC adapter
Q. While turned on, the laptop will switch to battery power even if connected with the AC adaptor (sometimes during boot-up, or after a while) until the battery drains out, he then goes to hibernation (the battery light is off). If no battery in the laptop, it will shut down, and the AC light will blink very fast. The battery (li-ion) will only charge up to 10%, where it then jumps right up to 100%, and will discharge from 100% to 90% then jump to 0%, go to hibernation, and fails to complete the process, shutting down. The adaptor makes a small “camera flash charging” sound, stabilizing at 19v. When charging, it repeatedly makes the “charging sound” Faulty AC adaptor? Or Faulty battery? Or Both?
A. First problem: The laptop switches to battery power even with connected AC adapter. Most likely you have a faulty power jack. It’s either broken or loose. It’s a known issue with laptops and you can fix it by replacing/resoldering the power jack or relocating it outside laptop case.
It also could be a problem with the power cord. Find a multimeter and check the AC adapter. See if the power cuts off when you jiggle the power cord. If it does, replace the adapter.
Second problem: The battery will discharge from 100% to 90% and then jump to 0%. It sounds like a bad battery.
Battery charging light is on even when power adapter is unplugged and laptop is stitched off
Q.The yellow light for battery charging does not go even after switching the laptop off and power jack is disconnected. Battery does not charge at all with power source connected.
A. First of all, try reconnection the battery if you haven’t done it already.
The battery plugs directly into the connector attached to the motherboard. If the battery charging light stay on even when the power adapter is unplugged and the laptop is switched off, it’s either bad battery or something is wrong with the motherboard. The only way to find the culprit is testing the laptop with another known good battery.
Also, you can try this. Remove the battery and plug in the power adapter. If the battery charging LED lights up even when the battery is removed, most likely you have a problem with the motherboard.
Battery charges only when the laptop is off
Q. Bought a Laptop without AC Adapter. I noticed it would charge the battery OK when the laptop was off but once in windows it would not charge the battery.
A. This is very important to choose the right AC adapter for your laptop. The output voltage MUST be exactly the same. If your laptop requires 18.5V you must use 18.5V adapter. The amperage should be the same or higher. If the laptop requires 4.74A adapter, you’ll have to find an adapter which provides 4.74A or MORE.
While using AC adapter alone or battery alone, laptop works. While using them together, I am getting a problem.
Q. While using AC adapter alone or battery alone, laptop works. However while using them together, laptop LED lights blinks and the power meter for battery drops down immediately to 0% critical level, whereas the battery LED indicator says it’s full. I tried to unplug the AC adaptor while it went down to 0%, then the power meter for the battery came back to normal 85%.
A. There could be a few different reasons why it happens:
1. It might be an issue with the BIOS. Make sure the laptop has the latest version of BIOS installed, update it if needed.
2. It might be a software related issue. If you have some kind of power management utility installed try uninstalling it and use Windows power management utility instead. Also I would try reinstalling the operating system if upgrading the BIOS or removing the power management utility does not help.
3. If you still experience the same problem even after upgrading the BIOS and reinstalling Windows, most likely you have a problem with the motherboard. Apparently the charging circuit is not working properly. I assume it’s not a problem with the battery. You’ll have to check the motherboard in this case.
Problem with my battery. 100% to about 40% the battery discharging normally then suddenly from 40% it drop directly to 2%.
Q. When I use only on battery, from 100% to about 40% the battery discharging normally (last about 1 hour) then suddenly from 40% it drop directly to 2%.
When I plug the AC cord, it won’t directly charge (the charge LED is still not on). After 10 to 20 minutes it then starts to charge the battery (the indicator say that it can be charged to 100%).
If I turn-off the laptop and then charge the battery, it won’t also directly charge but the delay is much shorter (maybe just about 1-2 minutes).
Is this the sign of a bad battery (when hot it can’t be charged?) or maybe a bad AC adapter (not enough power to charge the battery when the laptop is turned on?)
Note that this symptom is always repeating when I use the laptop.
A. From the first part of your complaint description I can see that you have a bad battery. The percentage might vary, but the process of discharging is the same – the battery discharges fine until some point and then the remaining charge suddenly drops to the minimum. You’ll have to replace the battery.
I’m not sure about the second part. Probably it’s a battery related problem too. Just in case check if there is a newer version of BIOS available for your laptop. If you find one, upgrade the BIOS.
The battery is 100% charged but it will die within a few minutes as soon as the laptop is unplugged.
Q. When I unplug the power it will run off the battery, the battery icon says it is 100% charged and I have 2+ hrs remaining, but within a few minutes I get the “critical battery level” message and it will die. When I plug it back into AC power the battery charge light comes on (and will remain on for over a hour), but I will have the same problem with it dying as soon as it is unplugged. Do I need a new battery?
A. It looks like you have a bad battery. Here are some behaviors typical for a dying laptop battery:
1. The battery charges normally (according to the battery icon) but as soon as you unplug the laptop, it dies almost momentarily.
2. The battery charges normally. When you unplug the laptop, it discharges normally until some point and after that point starts discharging very fast. For example it might take 10-15 minutes to discharge from 100% to 80% and then it discharges from 80% to 0 for 2-3 minutes.

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, i Have lenovo 0769-A63 laptop i have problem in my battery, when i put AC then my laptop is start,battery shows 83%(pluged in,Not charging). when i remove the AC System is cloosed is just like Cpu, its...


If thelaptop battery is more than 3 - 4 years old then the battery could be worn out.Rechargeable batteries have a finite number of charge and discharge cycles andwill lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up at all. OR Thebattery shows a 100% charge but when the adapter is disconnected the batterydrops off to zero capacity in a very short time. If the battery drops to anunacceptable charge level then the battery needs to be replaced.

My laptop won't charge. I have an acer aspire 5315 that won't charge, I had problems with the charging adapter before so I thought that was the problem and replaced it, the replacement worked for...


For a test -Remove the battery from the laptop. (leave it out) -Plug in the adapter and turn the laptop on. -Gently wiggle the adapter plugged in

If the computer powers off the solder and/or pins have broken loose from the DC jack. This is very common. Average repair bill is around $150, if your in the Denver Colorado Area I can do the repair for about $50
If it won't turn on while you wiggle the adapter and hit the power button then the adapter is bad again sadly

Laptop power charging stops and laptop later shuts down and no charging


First you should figure out what caused this problem. Here below are some possible cause:

AC Adapter Problems
If the AC adapter is not working properly, then the charging won't occur at all. An AC adapter, with lower than required voltage settings, will not be able to charge the battery. See to it that the AC adapter matches the laptop battery's requisite settings. A loose wire or internal breakdown, may render an AC adapter useless. Changing the adapter all together might solve your problem.

Power Management Software Problem
Sometimes, the problem is merely with the power management software. This is the classic case, when the laptop charges when switched off, but doesn't when the computer has booted. The software may have gotten corrupted which must be causing the problem. In such a case, go to the device manager section and uninstall the power management software. In case of Windows XP, uninstall 'Microsoft ACPI Compliant Control Method Battery listing' from the device manger section. Take care that you do not install any other AC adapter driver software. Then go for a 'hardware scan', which will automatically identify the battery and reinstall the latest version of the drivers again. That will restore the charging facility of your laptop.
Internal Charging Circuitry Problem
If neither the AC adapter, nor the power management software has a problem, then problem can be with the internal charging circuitry of the laptop. In this case, there is little you can do, other than send the laptop to the manufacturer's service center.
Bad Battery
If you have checked for all of the above, one of the main reasons, which could lead to the problem of laptop plugged in but laptop battery not charging is a bad or dead battery. Run a laptop battery test. If your laptop is quite old, this could be one of the most likely reasons. Get the battery checked from the manufacturer and check if it has exceeded its predicted recharge cycle limit. It is important that you get the dead battery replaced immediately with a new one. Laptop battery troubleshooting will solve the problem.

Hope this will help.
