I just got a Toshiba Satellite C675D-S7109 and installed Ubuntu 12.04 (64-bit) on it. I installed all the updates as well but didn't install the fglrx drivers. Seemed like it was working fine.
I suspended the laptop. Whoops, now it's a brick. No key, mouse button, or power button would resume it. The fan was still running and both power LEDs were on (one indicating the laptop is plugged in, one indicating it's powered on).
I held down the power button for 8s to force it to power off. Fan goes off, HD spins down, power light goes out, all as expected.
When I hit the power button to turn it back on, fan comes on, HD spins up, but it doesn't show the BIOS splash screen or anything -- just a totally black screen, like before I powered it off.
Edit: I removed the battery for a while and now it boots normally. Should I just disable suspend or is there a way around this?
Edit2: I tried
sudo pm-hibernate -- it didn't shut down the laptop but after forcing power off and powering back on it resumed just fine.
