I have a ThinkPad E530 but I suppose this is more a generic problem. I have recently upgraded from 4 GB to 8 GB RAM. The system worked perfectly for several weeks. Yesterday I completely ran out of battery on my laptop, and this morning the system wouldn't start - the fan starts turning, the red LED comes on, that's it. Screen is dead. I tried to remove the new RAM module and this seems to have fixed the problem. Tried to put it back in, same dead screen again. I'm just wondering if this is necessarily a faulty RAM, or if it could be a BIOS problem related to the dead battery from last night and a potential dead CMOS battery. I would like to know if this is possible before I go into the ordeal of returning the new RAM module and replacing it for an other one. Thanks for your thoughts!
