I bought an Aspire 5253 notebook for my daughter last year. A few months ago it developed an intermittent power problem. I thought it must be the power adapter or battery but when I finally got a chance to evaluate it turns out to not be any of the obvious things. And a search of this site and Google indicate this is a known issue. I'm hopeful that even though there is no recall and this notebook is off warranty that Acer will be wiling, as they apparently have in other cases, to fix the problem. In any case any information about exactly what the problem is would be much appreciated. The symptoms are the same as others have described. Sometimes the notebook powers up fine, other times nothing, no lights. The unit is in as-new condition except for this problem. I've purchased a number of Acer notebooks so far and this is the first problem I've run into. Help!
