I go to my local library to use their computers for email and visiting my favorite sites. If I run out of my allotted time, I go to a table that has outlets and plug in my netbook Acer Aspire One D255E, and do other stuff. Lately, I've noticed that when I plug in at certain outlets, my battery runs down, even though I keep it plugged in with the AC plug.
I checked on this site yesterday, and it said let your battery completely discharge, recharge, repeat a couple more times, and it will give maximum power. I bought my netbook 10 years ago after checking Consumer Reports' Buyers' Guide; it showed the AO D255E had a battery life of 8 hours, so I bought it. But I've never gotten more than 2 1/2 hours of battery life. I can't swear that I did the discharge/charge x3 when I got it--it was a return, the battery was already installed--but yesterday the battery completely discharged, and when I plugged it in to an outlet I know was working--it was powering the library computer I'm using--it wouldn't turn on.
I've told the library staff about this, and they say they'll have Facilities check it out. But I still find outlets that won't keep my netbook charged.
I bought my netbook 7 years ago; I don't think I've gotten to 1,000 charge/discharge cycles yet. Is something else wrong, or do I need a new battery? Thanks!
