I have a large Toshiba laptop that I bought a month ago brand new from Best Buy. I was using it the other day and the battery got low and went off. I have tried charging it but the screen will not come on. I can feel the fan running on the computer but nothing is on the screen. I took out the house battery and then put it back in. I heard it click on but the screen is still black.
That state might called comatose, during the shut down the battery gone low, so the system is in a hang state, after recharging to its full, then you power it on and the system try to recall the last status,sometimes needs reset and the system will work, other trick is remove the battery and PSU then push power switch several times to drain residual power and attach the battery and turn power on.If this will not work, the bios might be need reset, in this case you must claim your warranty service.

Took battery out and pressed power button a few times and tried to turn back on. Screen still black. Can still hear fan coming on.
