[SOLVED] [T430s] Ultrabay battery normal drain

#1 Post by whqdz » Fri Mar 30, 2018 4:38 am

Hello,

Since my fresh re-install of a Mint Mate 18.3 on my T430s, I notice that the ultrabay battery drains really fast.

My main battery (90,1% of capacity) drains at a normal speed, It can last 5hours with a light use, and ~3-4hours with moderate use (i'm going to switch to ssd soon).

My bay battery (model 43, 70,6% of capacity) last less than 1 hour. The problem is, when I was still using my old system (Mint KDE 18.2), this battery gave me ~2 or 2h30 of autonomy.

Do you think it's normal?

Tlp config file doesn't notice something about ultrabay battery (except tresholds). Do I need to set-up something somewhere? or calibrate?

Thank you :)

Monitor the rate of drain. I would expect that it actually drains at the same average wattage rate, but the % remaining suddenly jumps. This can be due to bad battery cell.

I didn't think about monitoring the rate of drain when using the 3 cell battery, I'm going to check this these next days, and if it's bad I'll check for another one once I find good prices :)

Thank you!

So, I just did a clean install with my new ssd, and the problem has been solved. I've lost some charges capacity on my ultra bay battery but I bought it as used on ebay for a really cheap price (17$) so it's really not a problem.

After taking a look at powerstat, it's the same Wh than with my main battery, and the drain goes lower. It's a good point.

The ultra bay battery lasts around ~2h-2h30 with tlp and turboboost enabled, no cpu frequency blocked. With a really hard use it lasts ~1h30, with a charge capacity of 64%.
