I've requested for help for this before but didn't receive help that fixed my system, so I'm hoping that I could get something more substantial with the experts!
I'm using a HP elitebook 840 G1 and lately I've been having slow start-ups. Instead of taking a few seconds to boot up, it now takes around 20-40+ seconds to boot up. Occasionally, when the system boot ups, a white screen shows up. On this white screen, there are two lines.
"The bios has recovered its identity data from the Embedded Controller due to data mismatch."
Then there is a 10 second countdown before my computer successfully boots up. Also, I realised that after this started happening, my "sleep" and "hibernate" function no longer works. Whenever I put my computer to sleep/hibernate (with open web browsers and folders, etc.), when I switch it back on, the computer seems to boot up as if I had shut it down. When it completely boot ups, I'm just greeted with my desktop. I wanted to email this to support, but (another problem) my serial number isn't recognized by HP for some reason.
I don't think that there are any installations that I have made that could have led to this? But I'm not all that certain when the problem actually started, therefore I can't give you a list of what I recently installed.
I'm using windows 8.1.
My elitebook 840 G1 uses an intel i7-4600U processor with intel graphics + Radeon HD 8750M, 1TB hard disk and 8GB of ram. All assistance would be appreciated!
