I've just brought less than 2 months.It's Acer Aspire 4551 and there seems to be a serious problem, I bought in outside my hometown so I don't know if the warranty still work. It's windows 7, the problem is the charging light keeps flashing even though its unplugged. It flashes all the time whether it's plugged or unplugged. When it's turned on it even says plugged charging so anyone knows some DIY solution instead of taking it to the Acer center?
still under warranty as long as not bought outside of your country so save your data & get laptop replaced ASAP.
