In this post I explain how to troubleshoot laptop battery charging problems. I will list most common battery failure examples and suggest some troubleshooting steps.

 

Example 1.

Laptop detects the battery but shuts off when AC adapter unplugged.

When you move the cursor arrow over the battery icon while the laptop is connected to AC adapter, it show the remaining battery charge and says “charging”.

The batter power meter utility (if available) also shows that battery is connected and charging.

But… as soon as you unplug the AC adapter, the laptop shuts off completely.

Possible problems:
1. The battery not seated correctly. Try reconnecting the battery.
2. The battery contacts got dirty or oxidized and the battery is not making good connection with the motherboard. Try reconnecting the battery a few times.
3. If reconnecting the battery doesn’t help, most likely the battery is bad and has to be replaced.
4. If you replaced the battery but the problem still exists, this is motherboard related failure. Apparently the battery charging circuit has failed. In this case the whole motherboard has to be replaced (or repaired on component level).

 

Example 2.

The battery not detected by the laptop.

The battery is installed and you know it’s connected correctly but there is a red cross on the battery icon.

If you move the cursor arrow over the battery icon, it says “no battery detected”.

Possible problems:
1. Most likely the battery is bad. You have a very good chance to fix this problem by replacing the battery.
2. If replacing the battery doesn’t help, this is motherboard related failure. The motherboard has to be replaced (or repaired on component level).

 

Example 3.

The battery discharges very quickly after it reaches some critical point.

The battery detected by the laptop and charges properly to 100%.
When you unplug the AC adapter, it take normal time to discharge until some critical point (let’s say 80%) but after that the battery discharges very quickly to 0%.

Possible problems:
This is battery related failure. The battery is bad and has to be replaced.

 

Example 4.

The battery charges only if the power plug positioned correctly.

You have to wiggle the power plug in order to charge the battery. After you find the right position, the battery charges properly.

Possible problems:
1. AC adapter failure. The AC adapter power cable is damaged. You can test your AC adapter with a voltmeter.
2. If the AC adapter works fine, most likely this is power jack (connector where you plug power adapter) failure. In this case the power jack has to be replaced.

In some laptop models the power jack is not soldered to the motherboard, it’s attached to a power harness.

In this case, you can unplug the failed power jack from the motherboard and replace it with a new one.

    I have a Toshiba Satellite M35x laptop. The laptop stopped detecting the battery, so I bought a new one. Same problem. Do you think my new battery is bad or I have another problem?

    Michael,
    In a Satellite M35X the battery connected directly to the motherboard. If you have exactly same problem with two different batteries and both not detected, most likely this is motherboard failure.

    Not likely. Even with a failed fan the laptop should turn on at least for a while.
    When you plug the AC adapter, do you get any lights at all?

    It’s possible the AC adapter failed while you were away. After that the laptop worked fine until the battery had charge and turned off after that. Now you cannot turn it on because the AC adapter is dead and the battery has no charge.
    Do you have a voltmeter to test the AC adapter?

    Turn on the laptop (without external monitor connected) and take a closer look at the LCD screen. Can you see a very faint image on the screen? The image could be so dark that you have to use a flashlight to see anything? Anyway, is the image there?

    If the laptop still runs on battery power but it just doesn’t last long, most likely you have a problem with the battery.

    his laptop has no display

    and the system is booting properly

    so I assume that there is something wrong with

    the connection of the lcd to the system

    or should I just re seat the memory

    Dear Laptop repair guy,

    Recently my Toshiba Satellite (big, about 3 years old) has been having battery problems. It has significantly reduced battery life, but worst of all it doesn’t warn you reliably about the level of charge, it just jumps straight from about 50% to the 5% warning red light situation.

    And now, for example, it is plugged in, 71% available, but NOT charging. Why wouldn’t it charge up to 100%?

    Is there anything I can do? Get a new battery?

    Yours

    Ned

    It’s hard to tell without testing the laptop with another known good AC adapter.
    Does your laptop work fine with the AC adapter plugged when the battery is removed? If it does, most likely the AC adapter is good.
    Most likely it’s either bad battery or possible motherboard failure. I cannot tell.
    I would try replacing the battery first.

    I just found this site and it is great! It is now book marked.

    I am trying to fix a friends Gateway MT6831 laptop. She initially had a hard drive failure so we put a new HD in and installed the OS and additional software. I had it up and running for 3 days with out any problem so I gave it back to her and it worked fine until the battery died. She plugged in the AC adapter and gets a blinking red light. So I now have the laptop again and when you take the battery out it is dead as a door nail. I followed you directions on checking out the AC adapter and it bounces around from .02 to .12 volts so I believe the trouble is the AC adapter. I would just like some confirmation before I tell her she now needs to spend more money for an AC adapter. Thanks Bill

    I think you need a new AC adapter. Shouldn’t be very expensive.

    Could be defective battery.
    Also, try reconnecting the battery a few times, it’s possible the battery contacts oxidized and reconnecting the battery will fix the issue.
    Is it a third-party battery? I really trust only factory replacement batteries.

    stace3610 Says:

    First, the website is great and extremely useful. Thanks!
    I have an Aspire 5310 which works fine in every respect except the following: the battery discharges very, very quickly. When on and plugged into the mains, it shows as charging (according to both hardware light and Vista system tray icons) but continues to discharge at an alarming rate (c.30mins). It even discharges when off! (Proper “off” not standby.) Takes about 8-10 hours to completely discharge whilst off (even when still plugged into the mains and with the “charging” light on) during which the laptop base remains warm around the battery/motherboard connection (even without AC adaptor in place). This happens with three different batteries that I can charge up without problem in another laptop.
    Another point is that once completely discharged whilst off, I need to recharge the battery elsewhere and then replace it in the dodgy Acer whilst the mains plug is in and on or it won’t start (with or without battery in place).
    Apologies for the long post but this is driving me mad!

    Have you tried another AC adapter. Maybe your adapter is faulty and doesn’t provide correct voltage? Just a guess.
    If it’s not the adapter, sounds like you have motherboard problem. Otherwise, it wouldn’t fail same way with three different batteries.
    I think most likely this is motherboard failure because you said “It even discharges when off! (Proper “off” not standby.)”

    I have the same problem as Jen – post #36. My HP HDX wasn’t charging either of the batteries I have. Now both batteries are dead, and the machine will only boot for a second then turn off when plugged in and with the battery installed. The machine won’t turn on at all with the battery out and AC plugged in. Unfortunately, my warranty expired a little over a month ago. HP customer support was useless – except for trying to sell me on an extended warranty plan. No wonder people love their MACs so much.

It wouldn’t turn back on at first, but after I removed and replaced the battery it turned on just fine. The next day my laptop wouldn’t recognize the charger. I quickly lost all the power on the battery and it hasn’t turned on since. There is nothing wrong with the charger, when pluged in to a different laptop it works perfectly. I did notice that once I plug the charger into my laptop, the charger will turn off. The green power light goes off immeadiately and won’t charge any other laptop until you unplug the charger from the wall and plug it in again. Please help, this was a birthday present and I would love to get it working again. Thanks in advance.

    Most likely it’s one of the following:
    1. The DC jack failed and has to be resoldered or replaced. It’s possible the failed jack shoring the AC adapter and because of the the adapter light goes off when it’s plugged into the laptop. It’s necessary to disassemble the laptop and take a closer look at the DC jack. If it’s loose of damaged, replace it with a new one. In the following post I explain how to replaced failed DC jack: http://www.laptoprepair101.com.....air-guide/
    2. If the jack looks normal and not loose, most likely this is motherboard related failure. I don’t think the laptop worth repair in this case.

    I have a compaq 515 notebook, a few months ago I was in my friends apt using & charging my laptop which frequently would get pretty hot when I would charge & use at the same time. This last time, there was a bunch of damp, white smoke pouring out of the charging jack (while still plugged in) the charger shorted out, I unplugged everything but it hasnt worked again.

    I was however able to continue using the laptop until the battery lost all of its charge. I had igo (mfr of the charger I was using)replace the charger i was using as at the time, as I thought it was a problem related to the charger shorting out due to a power surge or something. Once it was replaced, as soon as I would plug the charger into the jack on the laptop, the charger would turn off & no charging happened, all lights on charger go out & only for one second does a white light flash where it previously lit green to show the laptop was charging. I was going to buy a new battery as suggested by a friend but after reading one of your posts I’m wondering now if it’s the charging jack or a bigger problem. Laptop doesn’t turn on at all & doesn’t charge with any charger :( . Your help will be sincerely appreciated.

    The battery plugged directly into the motherboard. A new battery didn’t fix the problem, so it must be motherboard related failure.
    It’s not virus related problem, that’s for sure.
    You can try updating the BIOS if there is newer version available. If it doesn’t help, most likely it’s bad motherboard.

    Did you test the AC adapter?
    Find a multimeter and test voltage on the AC adapter plug. While testing the voltage, move the cord. If power cuts off, you have a problem with the cord.
    A bad AC adapter cord can cause intermittent battery charging failure.

    A bad AC adapter cord can cause intermittent battery charging failure.

    I have a compatible AC adapter, distributes various voltages.
    I use set to 18V and the multimeter reading is 18.2V.
    Can I try to set 19V? The reading multimeter is 19.4V.
    Even if I move the cable and jack does not change anything, the voltage is not interrupted.
    The load shedding is intermittent individually.

    cj2600 Says:

    Paul,
    Sounds like your AC adapter is OK.
    You said the screen looses brightness intermittently. Does it go from normal brightness to completely black screen or the screen just gets darker a little bit?
    If the screen just gets darker, most likely it happens because the laptop switches from full power to battery mode.
    Usually it happens when there is a problem with the AC adapter or DC jack.

    Sounds like a virus.
    1. Backup your files with an external hard USB hard drive.

    2. When you transfer files to another computer, make sure the computer has a good and up to date antivirus software installed. You don’t want infected files on another computer.
    3. Reinstall OS on the infected laptop.

    What do you mean by “computer will not work”?
    Does it turn on at all? Do you see any lights when AC adapter plugged in? More details please. How it’s failing?

    Good day,

    I have a compaq A900 laptop. It was given to me by a friend so i could check what the problem is but I’m currently at a loss.

    I have checked the AC adapter with a multi-meter and it is ok. I also dismantled the laptop and check the DC harness cable and it is also ok.

    The problem is, when i plug the AC adapter, the LED’s will not light up and it does not charge. I’m not sure if the battery is dead since i cannot charge it.

    Now the tricky part is, when I used a fully charged battery from a friend, the laptop works fine. There must be something on the motherboard I’m missing. I checked all the pin connections of the motherboard to the DC harness and it seems ok.

    Any information will be greatly appreciated. Thank You very much~!!!

    If your AC adapter works properly, it could be one of the following:
    1. bad battery.
    2. failed DC jack.
    3. failed motherboard.

    Hello,
    I have a Compaq Presario F500, and I am unable to charge my (now exhausted) battery. I had one or two instances where despite being plugged in, the ac adaptor didn’t charge it. Then, the battery ran out while plugged in. (This makes me think the battery was OK.) The blue light at the plug-in point no longer lights up, and it doesn’t recharge. Someone at work tested my power adaptor and said it seem to be Ok. Is this a battery issue, or do you think it is a connection problem? Hope you can help.

    Could be a problem with the DC jack (power socket). Can you make the light work if you adjust position of the power adapter inside the socket?
    The DC jack located on this power board. You can try replacing the power board and see if it fixes the problem.

    Could be one of the following:

    I have a Gateway laptop that is exactly 2 yrs old. I was having this problem at first where it would basically say it wasn’t charging and I’d have to keep it plugged in. One day it just unexpectedly powered off and wouldn’t power back on. If I push the power button it makes noises as if it’s about to power up and lights come on but then it just powers off after about 8-10 seconds. Any ideas of what this might be? I’m hoping it’s a cheap fix because I can’t afford a new laptop at the moment. I’ve been told so many different things I don’t even know where to begin to diagnose the problem. Any help would be MUCH APPRECIATED!!! Thanks!

    This could be just simple AC adapter failure. It’s possible the AC adapter went bad and the laptop stopped charging the battery after that.
    Now you cannot turn it on because the battery doesn’t have enough charge.
    First, I would test the AC adapter. You can do it with a multimeter.
    Alternatively, you can test the laptop with another compatible AC adapter.

    It’s not very clear if the laptop turns on at all. What happens when you push on the power button? Does the laptop start at all?
    By the way, you can test the AC adapter with a voltmeter.
    It’s possible the AC adapter is dead and the battery doesn’t have enough charge to start the laptop.

    I have two identical ‘Dell inspiron 1420′laptops, Dell#1 was not charging neither powering on when plugged in…. Battery in #1 was placed in Dell#2 to determine if battery was good, and it did charge with no problems.

    After switching back batteries, Dell#2 was not charging but able to power on when plugged in only.

    Now Both Dell will not charge batteries in their respective computers.

    Unfortunately, I think there is a problem with the motherboard. Probably the battery charging circuit failed or something like that.
    Just in case, try starting the laptop just form AC adapter with battery removed. Can you?

    First of all, here are Toshiba Satellite A55 disassembly instructions if you need them:
    http://www.irisvista.com/tech/.....-guide.htm

    If the laptop doesn’t turn on at all, there could be a problem with the power button board. Shown in the step 10, it’s above the keyboard.
    There could be a problem with the DC jack.
    Also, could be dead motherboard.
    I cannot tell which one is failing without looking at the laptop.

    Most likely this is battery related problem. Replace the battery.

    This could be a problem with the battery charging circuit on the motherboard.
    Normally, the laptop would run from AC adapter when the battery removed.
    Also, I would suggest testing the laptop with another power adapter. Maybe your original adapter failing (not providing enough power to start the laptop and charge the battery).

    Try this. Unplug the AC adapter and use the laptop on battery power until it discharges completely.
    Now plug in the AC adapter and try charging it. Will it go above 91%?

  100. 100
    Josh Says:

    Now it wont charge above 0%

  101. 101
    cj2600 Says:

    @ Josh,

    If the laptop will not charge two different batteries, most likely this is motherboard related problem.
    Yes, there is a chance of bad AC adapter. Maybe it’s not providing enough power to charge the battery but I think this is motherboard issue.
    Remove the battery and run the laptop just on AC power. Does it work this way? If yes, probably the adapter is good.

    I’m not familiar with this netbook, but if the battery is built in there is not much you can do.
    You’ll have to use it as is on the AC adapter power or buy a new netbook.
