I did try that once, and somehow it went horribly wrong - the machine |
| 27 |
became *very* unresponsive to keyboard and mouse, as if it was applying |
| 28 |
huge amounts of CPU throttling (not freq scaling) |
| 29 |
|
| 30 |
So I gave up. I never use this machine as a classic laptop anyway, to me |
| 31 |
it's a desk workstation that I can suspend and carry home in a backpack |
| 32 |
with ease, so it's always plugged into power to use :-) |
| 33 |
|
| 34 |
I only ever need the battery for maximum 20 minutes in review meetings |
| 35 |
every two weeks, so I just kinda learned to live with it.... |
