Issues with Lenovo ThinkPad T430s

I was facing two weird issues with my laptop (Lenovo ThinkPad T430s).

Hibernate:

The battery was working fine normally but when I used to hibernate it in the night / EOD, and next morning when I used to wake it up, I used to find the battery completely drained. Lenovo guy installed few softwares and update many drivers but didn’t help.

After analyzing I realized that the “Power Plan” is creating the issue. If the “Power Saver” option is selected and the laptop is hibernated, it used to resume normally; but while hibernating, if the “Green Desktop” option is selected, it used to drain out entire battery. So, if you are also facing same issue, whenever you hibernate, select “Power Saver” option then hibernate—problem solved J

Audio not working:

This was again weird: normally we keep our system on mute, using the “Mute” button for speaker on the laptop.

 Whenever we need to enable the sound, toggling that button on the board disables the soft button for speakers. This always required machine restart, which is irritating.

I found a work-around that, if you open up device manager (run “devmgmt.msc”) >> go to “Sound, video and game controllers” and disable and then enable the “Realtek High Definition Audio” driver, it will restore the sound– well, that’s it J

Feel free to leave your comments, if you have found out proper solutions for these issues.
