How to revive your dead laptop battery
Does anyone of you here had an ‘old’ laptop whose batteries can’t even last 10 minutes? Well, instead of playing with it by tossing it into an open flame to see what happens or throwing it in the dumpster where it’s ecologically not helpful, why don’t you try reviving it?
Yes you can! With some newspapers and a fridge of course. According to the ‘expert’ you need to take those old batteries out of the casing, wrap it in newspapers (thick enough so not much moisture will be in contact with the batteries) and leave it for like a week or so. Let it cool down in room temperature after that for at least a couple of hours or a day.
Once it has settled down in room temperature, wipe off any traces of moisture on the batteries, put the batteries back in its casing, stuff it back in the laptop and charge. (Do not switch the laptop on!) Make sure it is 100% powered up.
Please take note that there is no guarantee whatsoever that this will work and if your fridge got contaminated or your warranty void, it’s all your responsibility.
For a better explanation of the above technique, why don’t you check out HTNet’s blog post. He does a better job at explaining it.

Azmeen- Well, good stuff are supposed to be shared
Yes, I’ve read about this before. Never tried it though.
BTW, the ad at the bottom: “Ad: it may not work with bathroom lights that are battery powered.” which ad network is that from?
This is interesting.. will give it a try when I’m free
Many new notebooks provide a hard-wired On/Off switch for the Wi-Fi radio for this reason.
To save even more power go to the Control Panel, select System–>Hardware–>Device Manager, and disable the following items: Ethernet adapter, infrared transceiver, and Bluetooth radio . You should do this beacause having Bluetooth enabled and not using it actually consumes quite a bit of power.
Thank you for this outstanding article.I thought Centrino was the best technology for laptop battery performance.
thanks,Other small improvements in battery life may be gained by the ability to turn off USB ports individually to save power.
