By accident the preinstalled Toshiba Power Management stopped working. I’d experienced this once before, and it had something to do with the software not being able to read from the registry. This time I didn’t have time to fix the problem, so I decided to continue without it. I’m running the Notebook Hardware Control as my tool of choice for undervolting the processor on my Tecra M4.
I had previously been under the impression that I needed the Toshiba Software to control the fan on my laptop, but after a few hours I found out that because I’m undervolting my (almost) stripped computer (running AVG anti-virus software instead of the hungry Norton Suites and almost none of the preinstalled Toshiba utilities) the processor isn’t running hot anymore and the fan doesn’t kick in at it’s highest speeds. The temperature stays between 50–52 and 58C.
I’ve updated the undervolting settings from last time I wrote about it. Now I’m running at 0.988V at full speed, and 0.716V at the lowest speed. I’ve also noticed that running in either “Performance”– or “Max Battery” mode makes the processor running colder than when using the dynamic switching or battery optimized modes.
In addition, undervolting the computer gives me a bit more battery. I’m usually getting almost three hours on my Tecra now. It’s the best computer I’ve ever had. Honestly!
