Hi, stumbled across this forum to get a definitive answer on how secure these are as ive been reading mixed things. Long story short left my acer c720 in a library in sleep mode, went back later and there was no sign of it. It was encrypted with an 8 digit pass containing numbers/letters. Now as with any computer its full of personal details, emails, financial info, the list is endless. Now people are telling me it can be brute force hacked even though its 128 bit AES?And even cold boot attacks are a risk, even on ddr3 ram? Anyone clarify this for me, cheers
