This question already has an answer here:
I have a Lenovo x120e that is not booting properly. When I turn it on, it just opens to a blank screen.
The machine is running Ubuntu 10.04.
Main Details: I shut the lid of the computer while it was running, and then opened it later and noticed that I couldn't get out of suspend / hibernate mode. I subsequently powered it down by holding the power button. Now when I turn it back on, it just opens to a blank black screen, as if it is still in suspend / hibernate.
Other Details: The 10.04 operating system (A) was installed while this HD was in another laptop. Since I moved the HD into this machine, I have been booting another OS (B), and never updated drivers in A to work with this machine. (Does this matter for this particular situation / problem?)
What I have tried so far: I found the REISUB method here but I don't have a SysReq button.
What are my next steps to troubleshoot / solve?
