battery not recognized?

hi there, sorry if im posting in the wrong area. my aao 160gb 512mb version does not recognise the battery for some reason, but still works, the funny thing is that when i put the charge off it still works, the same length that the battery normally does but for some reason there is the ac sign on and when i click it it says running on ac power as well as battery not present. has anybody else had this problem before? solutions? by the way originally it was on linux but ive installed rons tinyxp about 2 and a bit months ago.

 

I seem to remember bios 3309 fixes this problem?

I have similar problem. Mine configuration is AAO 150 pink, 160GB 6 Cell battery. Bought it 14 days ago.

First time when I was charging it charged battery ok, but from now on it does not recognizes AC power adapter at all. It only works on battery [which has about one hour of power]. The system already came with 3309 bios but anyway I tried to reflash without any success.

The old rule of Acer very crappy support is proven to be working well. By looking menu forums I noticed that in every AAO specialized forum there's at least one this like thread on each page with very small amount of users that solved problem with 3309. So even they said 3309 resolves this issue it seems that its not or in very limited numbers.

Anyway as last resort I will try to downgrade BIOS to an older version and upgrade back to 3309 again. I would also like to add that MSI Wind X90 which is 99.9% same machine does not suffer from this kinda issues [in these numbers ofc]. Now I can only blame myself for not paying few euros more for 2 year MSI guarantee and not considering old experiences with Acers bad support and engineering.

And yes for all other potential users with same problem:
I spent whole day trying to find documentation for flashing utilities and found none, but I found a bit of explanation using Google translate on some Chinese board which pointed at platform.ini file in Windows version of flash. There I found option to run flash process without AC adapter. For all of you using AAO with Linux or prefer using flashit.exe Acer has a hidden meaning in their support documentation - SUCK IT.
