Normally, charging cicuit of the laptop which is part of the Motherboard has the problem. This happens if you keep the old battery installed even if the battery is already futile. Best solution is to bring it to the nearest shop.

Hope this helps.

If your new battery it is not faulty, then It is possible that you have oxyde on battery contacts, or a broken battery contact inside your laptop.
You need to use a multimeter to test power from battery recharge slot contactst on laptop if there is power with right voltage, then new battery is faulty, if there is no power then is a broken contact inside laptop

When I unplug my Dell laptop, the battery charge drops to 70% or less. Do I need a new battery? How do I know it isn't my AC adaptor not working? Thanks!


Hello.

I believe that it is your battery. It's just not holding a full charge. Over time, batteries do fail Keep your battery until it completely fails or becomes inadequate for you..

If your adapter wasn't working, your battery wouldn't charge at all.

Hope this helps.

My Acer Aspire 9805 battery was replaced. For


It could be an AC adaptor issue.

It should boot when connected directly to the power outlet through the laptop adaptor. If it is not boot, then the adaptor might not be supplying the needed power to boot it up.

If it is possible, try to isolate the issue. Charge your new battery using another laptop. Then plug it in your laptop to see if it works. If it will work, then it is the AC adaptor of your laptop that is defective. If the charged battery still won't make the laptop boot, then there is something wrong with your laptop hardware. If could be a motherboard issue of your laptop.

Battery will not charge compaq presario v5000


I would try replacing your ac/adaptor (power plug) before troubleshooting any further. It sounds as if the adaptor is faulty. Check eBay, you can get a replacement for less than 10 dollars.

Dell Inspiron 9400 will not charge - AC adaptor not recognised


Does the laptop power up just no charge the battery? If the laptop does not power on then you may have a bad power supply in the unit. If it does power up than you most likely have a bad battery connector of blown fuse on the motherboard. The flashing of the BIOS is done with a bootable cd or floppy but this will not keep the new battery from charging. The reason Dell states that you need at least 10% battery to flash a BIOS is because if your AC power goes out while you are doing a BIOS upgrade and you don't have battery power the BIOS will be incomplete and your laptop will not boot again without replacing the motherboard.

Inspiron laptop Battery won't charge


Try taking out battery and plug in power. If it works, battery is faulty. If not,
Try taking out your hard disk plug in power, if it works, hard disk is faulty. If not,
Try taking out memory card, if there's a sound, memory card faulty. If no sound, it's your motherboard that is causing the error.

Note: If machine is under warranty no need to pay for the repairs.

Plug in battery, power light and fan noise cycles on and off


I think it probably went into hibernate. Remove the battery while unplugged from the a/c adaptor for a few minutes. Plug it into the a/c adaptor, and see if it will boot up.

Want stay charged


Sounds like a bad battery cause its not keeping a charge. Try a new or known good battery and see if it will charge and then unplug the ac adaptor to see if the laptop stays on.

If the laptop stays on with a different battery charged then your old battery is bad. If your laptop doesn't stay on with a known good or new charged battery without the ac adaptor hooked up then its a bad motherboard.

Both batteries could be dead. But if you bought a new battery, it's unlikely. I don't know what green light you see, but if it's on the power adapter, it just means it's turned on--not that it is charging.
Two possibilities: Your power adapter is bad or the motherboard is bad. Because you say the computer works if plugged in, then you have ruled out the adapter.
You should be checking/cleaning the battery contacts and if all else fails, going for a new motherboard.

Laptop not showing light, power button not turning on, AC adaptor light constantly beeping faintly


Unplug the power cable... Hold the power button down for 15-20 seconds... Plug cable back in and check for light... If this still didnt work, then unplug cable again, take battery out, wait 10 seconds.... Put battery back in, plug cable back in and this should allow you to boot...

Compaq evo n610c battery not charging


Hello All;
I used to have these same problems. I replace my BIOS battery, which I know was dead, because all settings get reset when I unplug the power and remove main battery. You might not have to replace it if its still good. Back to the main battery problem, You have a good change of solving this by going into BIOS, and under Tools there is a Battery Calibration option. Do the calibration for the main battery and-or other optional batteries attach and it will most likely solve the problems. This calibration process will take a long time; 1-charge, 2-discharge, 3-recharge, so leave it over night or however.

There was a mention of updating BIOS. This could solve the problem too, because BIOS controls the charging unit. Also, make sure you have Compaq Power Management install on your OS, (download at hp.com).

One note: it will not charge if the battery is about 93% or higher. 93 is not exact, but close to 90%. so test by discharging to below 90% and it will start charging again.

If anyone tries this, leave a post of your success or failure.
