Clevo p150sm with GTX 980m powers off when running on battery

Hi all,

I had pretty good success with my GPU upgrade a few months back, although at the same time I realised my battery was on it's last legs. I bought a replacement that I had to send back as it was faulty, but now I have got a working one and it's running very close to the edge in terms of power draw. If I run any heavy GPU benchmarks, or even max out the CPU for any length of time on battery it will just power off in an instant. It's doing this both on Windows and Linux (the latter with the nvidia card completely disabled).

I'm running Prema's Mods for both Bios and vBios. Is this something that other people have experienced? Shouldn't the power consumption be scaled back when running on battery just for this reason? Perhaps this is something the prema BIOS turns on/off, but I can't seem to find any other references to this.

Any ideas how to manage this? Thanks in advance,

Pete

 

It's supposed to, yes. No shutdown on AC power, right? Are you able to get your hands on a spare battery to test?

 

Nope, AC power is fine, barring very extreme power draws (way more than we're talking here). It does this with both my old battery and the new replacement.
