Hello,I have an Acer Aspire One, not quite 2 years .It has stopped powering up for me. At first the battery light would come on & off periodically & so would my blue start up light , but it wouldn't come on .Today I'm trying it & the blue light will come on & go right out again ,but I'm not seeing the battery light at all.It still won't start up & stay on. Do you think its the battery gone in it??
