Hi everyone, i'm back again lol.
Anyway, i haven't changed the battery yet (still waiting for my laptop to arrive, don't wanna to do paypal trans using my phone)
But from the reply from goodvibes (post 12240, pg.816) regarding the bad connection, i've decided to crack it open.
When i opened, the date on the battery shows around dec.2011.. It's been long enough, but the battery is still in good physical condition (At least, it doesn't bloat)
Then i pull the connector, give it some deoxit, sanding other connector (the male one), cleaning it, and plugging it in, and voila.
At least it solves the second problem. Thanks goodvibes
The fist problem still occurs btw.. I wondered if that will change if i calibrate the battery?
I guess i will calibrate it today, i will let you know the result
