I've owned the above laptop from new for about 2-3 years. A few months ago I downloaded Windows 10 when it first came out and my computer prompted me to do so. I had no problems initially but more recently I haven't used the laptop for a few weeks. I started it up yesterday and when it prompted me to sign in to my windows account I noticed that only certain keys on my keyboard would work. For example the delete button does nothing, certain numbers such as 8 and 3 do not work - whilst all other numbers will work. The letters g and h, also the esc button and space bar do not work?! I had to use the ease of access screen keyboard to log in. Is there a fix to this? If my laptop isn't compatible with Windows 10 then why was it working fine before? Is it possible a recent update that has downloaded is actually not compatible with my laptop? Please help as its so annoying.
