In stead of carefully reading the manual (as it's in the most cases when advice is needed) I didn't charge my Li-polymer Battery on T101MT immediately after using it for the first time. In stead, I used the capacity the battery had by default until the netbook switched off, and only then I charged it completely.
Question: did it cause a significant damage to the battery capacity? I heard this kind of batter doesn't have a "memory" ...

youre correct Li-ion and Li-polymer dont have the memory effects of old batteries. If youre storing your battery/netbook without use for a while make sure its at around 40% charge and its apparently better to not do full charge/discharge cycles except every few months and just keep it topped up when you can.

You might want to try this forum as its where most T101MT posts are currently going as your 10" model doesnt yet have a forum.

Thank you for the hints!!!

I doubt you harmed the battery.

While Li-Ion doesn't suffer from true "memory effect", the battery gauge can become out of calibration, as it tries to guess remaining capacity based on voltage, how much power has been sucked out, etc. This is a digital effect, and has nothing to do with the chemistry or true performance.

If the battery gauge appears inaccurate, the gauge should be re-calibrated. To do this:
1)Fully charge the battery.
2) Start the computer and enter BIOS setup.
3) Leave the computer running until it powers off
4) Fully charge the battery.
To "re-calibrate".

The same is true of any Li-Ion device with a funky gauge: Phone, camera, etc.

Re: storing at 40%: This is an issue if you're going to be storing it for weeks or months. For hours or days it doesn't really matter. However avoid leaving the battery in a fully depleted state for any period of time.

In my experience Li-Ion is a crapsshot. I've seen people baby batteries (Remove when on AC, etc) have the battery die in a couple years. Other times I've seen battery left in, laptop running 24x7 still with 80% of usable capacity after a couple years. I have a 13 year old Li-Ion battery that still gets a couple hours.
