It was just working perfectly one day ago but when I turned it on today it is not working at all...Iam unable to use it in BIOS...Even I cannot go in the Bios or press f2 or f12 or go into safe mode by pressing f8...Co not even one key is working...I talked to acer support agent and he is saying that it is a Bios issue and is not related to hardware and is asking for $60 to get it solved by their technician..I cant pay them because I dnt have a credit card and also it a big amount ._. and iam not taking my notebook to a local repair shop because there is a risk that they can damage it..!! So please help me 🙁 The model of my Acer Notebook is 'Acer Aspire One d250' !!
