How to Fix a Dead Netbook Battery
Disclaimer: I am not a pro, nor am I responsible for anything that occurs. However, I have tested this on my own netbook and it worked.
Have you recently bought a netbook or mini laptop only to have the battery stay at 0% when charging? There are usually three reasons why your battery is not charging:
First, your battery’s meter was completely drained until it was at 0%. You might not remember the time that this occurred, but apparently it did. Second, you need to update your BOIS. Third, you need a new battery. However, this would only be so if your netbook is old or has been used excessively.
The first thing you should try in fixing a dead netbook battery is charging your battery for 12 or more hours. So shut down your netbook, plug the charger in and let it sit for 12 to 15 hours. There is a chance that you drained your battery completely, now we need to bring the charge back as it was done in the initial setup. Once the charge is complete you need to power on your netbook and see if it will show a 90% or higher charge. If so, then this method worked and your battery will now charge normally. However, if this method did not work, move on to the next step.
To fix your dead battery try this second method, which requires that you update the computer’s BOIS (basic input/output system). You can do this by going to the company’s website and searching for “BOIS update.” An example of company names are Dell, Acer, and HP. Update the BOIS and follow the instructions clearly. This should fix things up with the battery; if not, move on to the next step.
If nothing seems to fix your dead battery then you're going to need to buy a new one for your netbook. If your netbook is under warranty you can probably get the battery for free. If not, then search online on ebay or amazon to get one for a discounted price.
