But if you're carrying it around and switching back and forth between plug and battery power every day....why bother removing the batt?

I took off my battery after a full charge and just left it on my desk. 6 months later, I just couldn't charge the battery anymore. The charging lights are on, but when I tried turning on the laptop wihtout the battery, it just won't start. In fact, it would short-circuit the charger, and turn off my lappie. Scary... My advice is let the battery run a bit once every one/two weeks (to maybe 80%). Then recharge it. Li-ion batteries need a full-charge all the time to keep them from dying. Using them until it's empty is not recommended. First hand experience.

Any side effects to this ah? last time i thought since i am using it like desktop, take out battery la.. but if suddenly unplugged w/o shutdown, all gone.. I have my computer on all day. and it is plugged in to power supply… so always battery at 100%.

That means, it does not REQUIRE the user to discharge the pack before charging it. jase – Then the notebook itself must have costed the customer his/her whole lifetime of savings?

You are more likely to degrade the Li-ion battery by depleting it, then recharging, depleting it then recharging again. You would think people who want to preserve their batteries would actually so some battery research beforehand.

i recently bought a new notebook but this thing’s size is damn bulky and of course heavy (yes, this is a cheap notebook). so i have removed the battery (not going to use it anyway) to reduce the weight and stored it inside ‘bakul sampah’.

and before you tembak me kow-kow, i bought a notebook so that i can use it at my home and office easily.

more information please…
