I've had an Acer Chromebook for a little over a year now. Aside from a couple of months ago when it wouldn't connect/stay connected to my school's WiFi, I have had no major issues with it. Until last night. My battery got low so I plugged it in like normal, except this time it made a high pitched whirring/whining noise, so I unplugged it and it stopped making the noise. My battery got down to 1% so I plugged it back in and it made the same noise. I closed the screen and it stopped making the noise, so I left it plugged in and went to sleep. When I woke up this morning and turned it back on, once it was on it started making the noise again and it was still on 1%. I've been using it plugged in for about an hour now, every few minutes or so the noise stops for about 15-30 seconds. My laptop shows the charging symbol but despite having been plugged in for almost 12 hours, it still is on 1%. I performed a hard reset since everything I have on my Chromebook is stored in my google drive and that didn't help either. I googled the issue and the exact thing hasn't seemed to have happened to anybody else. I tried google support and they didn't have any answers for it there aside from contact the manufacturer. I tried doing that I spoke to a nice gentleman who told me that Chromebook was still under warranty and tried to transfer me to another department but nobody picked up. I use my Chromebook to take notes in 4 of my 7 classes so I really can't have it dying on me before I even get to class. Does anybody know if there's any way for me to fix it myself or will I have to take it someplace to get it fixed?
