Title:
[HP Probook 4540s] Load/Unload Cycle Count
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
I have a little a bit of a problem with my Ubuntu (and Mint on other laptop -
same problem)
My Load/Unload Cycle Count is currently at 92125.
The problem is that Load/Unload Cycle Count get higher every time I use my
laptop on battery mode.
With AC it seems fine, but with battery in a matter of a few minutes (1-2) my
Load/Unload Cycle Count gets higer for 3 numbers.
I checked it on Windows, and it was at 92117. Then I booted in Ubuntu
and the number climed at 92121. I used laptop on AC for 20 minutes and
then it was at 92122. Then I unpluged AC, and used my laptop on
battery for few minutes and the number was at 92125. Then again on AC
for 15 minutes and it was at 92125. So it gets high quickly on
battery, very quickly.
Also I hear scratching noise of HDD when Ubuntu opens Files, Firefox os
something like that.
On Windows I almost never hear that, only when doing something hard for HDD.
This is happening on my 750GB Seagate disk.
Running Ubuntu 14.04 LTS with Windows 7 dual boot.
