I have a strange issue with my Laptop running Linux on SSD.
SanDisk Ultra Plus 128 GiB SSD, SDSSDHP-128G
After installing Ubuntu 14.04 I have found that battery life on my PC while shut down ( yes you read that right) sux. The battery is fully charged when I shut the pc down, Over night I find it has been drained by about 20%, If I fully charge the battery, and do not use the laptop for 4 days the battery is down to 17% charge.
Sure I hear you all say the battery is no good get a new 1. But no the battery is fine. How do I know? I have been testing this across 3 Hard Drives and 4 operating systems.
Same Issues with Kubuntu 14.04
Option 1 see above.
Hitachi HTS 54755
With this setup I can charge the battery, Leave my laptop for a week and the battery is down by 1 or 2%
Same as option 1 and 2, Just that Windows 7 is installed, No unexpected battery drain.
I have Puppy Linux on a USB, I can boot my pc up from USB, charge the battery shut down the pc, Again no problem.
I have tried sudo poweroff while using Ubuntu and still the same result. This only happens when I boot from SSD, I have checked all the settings and cant find anything amiss.
It seems that the PC is not shutting down With SSD in it ( No lights flash and the PC seems to be shut down.)
This issue has driven me mad to the point that I removed the SSD from the laptop and run a HDD in its place.
If anybody else is having this issue please let me know.
Regardless of Operating system, While booted I get normal battery life around 2 to 3 hours use, Only Puppy gives me longer battery life.
I even fully charged the battery took it out of the laptop for 2 weeks and only lost 3% charge.
