Hi guys it's me again

bothering a little bit here, because I know I can really trust you buddies, there're a lot of skilled and knowledge-full people in this forum

.

So I've got an issue with my brand new ASUS G60VX I just bought yesterday (my Gateway M68-64FX just died and they gave me a replacement, just paid $160 for the difference) suddenly 10min ago checked my battery charge status on Windows 7 Home Premium x64 and it said "Plugged in, not charging".

I was like "WTH!" I don't think it's my battery 'cause it's brand new

,then I was searching the web for some info about and it seems I have to calibrate the battery (fully charge it and fully discharge it a couple of times) to get its full potential.

But then I found out that calibrating the battery was NOT necessary with today Li-Ion and Li-Poly batteries unlike older NiMH and NiCd batteries. In fact that would put a huge of strain on the battery cells and could reduce battery life.

Now I'm kinda confused , now it's charging again but It really worried me , do I really need to calibrate the battery or not , guys?

this is normal.

the battery won't charge 100% of the time. if you are using the laptop and can plug it in, do so. the laptop will manage charging the battery.

you still need to calibrate the battery... charge it fully. if it's brand new charge it for 2-3 days... then set your power management to do nothing when the battery gets low. close everything and let the machine run overnight to run the battery down completely. this establishes a baseline so the laptop knows what dead and 1% are...

now set your laptop to notify you when your battery is 50% and hibernate when it hits 15-20%...

As far as telling it when to hibernate, it's all really a matter of personal preference. Congrats on your new lappy.

It's a fact that calibration is unnecessary. Even when people say "charge your device completely the first day or you will harm the battery" - it's all bullcrap. You do not need to perform any complicated recharge cycles or other procedures to make your battery work optimally.

This is exactly it. You might have been told that batteries work better if you allow them to fully discharge before recharging. This is only true with nickel-based batteries. Lithium cells have a set factory life (how long differs between batteries) and are best kept as charged as you can keep them. There's no "calibration" or "conditioning" necessary, just use it as you normally would.
