Try discharging the battery flat and recharge again. if still cannot, yo will have to replace the batt. always remove the batt from the notebook when it's running on a/c.

AC Adapter issues Q & A.


<p><b>Laptop switching to battery while connected to AC adapter</b><br /> <p><b>Q.</b> 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?<br /> <p><b>A. </b>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.<br /> <p>It also could be a problem with the power cord.

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. <br /> <p><b>While using AC adapter alone or battery alone, laptop works.

Hi Faiz,

It the battery is malfunctioning then you need to check if your machine is still in warranty and call the tech support hotline of Lenovo and ask for a replacement free of charge. However, Lenovo ships a replace to US, Austalia and New Zeland Address only. If your laptop is purchase from other country then you need to get intouch with the seller of your laptop

Lenovo Hotline: 1877-453-6686 or 1877-4LENOVO select Option 2

Thanks for using Fixya.

Make your Lithium Laptop Battery last longer.


Hello folks,

Although I usually offer advice on backing up files or recovering them, I have been asked a lot lately how my 3 year old laptop still runs 1:45mins on a standard battery when many peoples 1-2 year old laptops can barely last an hour.

Simply put, most people do one of two things wrong. Both are common misconceptions and easy to remedy. First I've heard countless people tell me they pop the battery out of their laptop and toss it in the desk drawer until needed, often months. Second I have been told by more people than I can count that they leave their laptop plugged in 24/7 for most of the year.

Bottom line, although popping it out and leaving it in the drawer is less harmful to it's lifespan, both ideas are wrong.

The shelf life of most unused lithium batteries is shorter when unused than ones being used properly. The lifespan of a battery that is constantly being trickle charged is even shorter.

Most batteries in modern laptops are 4-6 cells, designed to give about 2 hours of charge and should last 3-5 years with charge life starting to degrade in the third year.

A "stored battery" has only 3 years of shelf life due to extended times sitting discharged and one that is trickle charged 24/7 may burn out in as little as a year.

Many laptop manufacturers have taken measures to improve this but ultimately the best thing for your battery is to use it. If you currently run you laptop plugged in 24/7, unplug it every night after you shut it off, then when you start it in the morning, let it run an hour before plugging it back in. This will give the battery both down time and exercise.

If your battery is in a drawer somewhere for safe keeping, put it back in the laptop, run it down then charge it over night and run it down then recharge it one more time. Store it back in the drawer charged and repeat the cycle at least once a month.

These tips will help drastically improve you batteries performance over time. My 3 year old laptop only ever got 2 hours of battery life and still gets 1:45 with no power saving measures, give it a try.

Acer laptop how to get the battery to last long?


Batteries last about a year depending on if you let it fully discharge before recharge the very 1st time you use it.
the real average is to expect about 6 months usage before it degrades. by one year you'll be lucky if it gives you 30min charge.

Battery back up is limited to 1 hour only


Did you do a full cycle charge when you got the Laptop? When you buy the Laptop you have to use the computer on battery till the battery dies and then charge battery for 12 hours and you repeat that another time. Most likely your battery it is damaged. Maybe you call the company and they might replace it for you.
