it started 2 days ago.
Day 1. when laptop is on battery everything works great. then on 10% I put the power supply on and touch pad started to malfunction. the mouse either not working or not working well. remove the power supply and all is normal.
Day 2. touch pad works great with or without power supply. now I have a problem with the internet. when on battery all is ok but with power supply on not internet. I can see the router, it's connected but no internet. remove the power supply and all is normal.
Day 3 (today 19-mar-2014). internet and touch pad works perfect with or without power supply. Now the problem is with the HDMI port. with the power supply on it doesn't work, no signal. with the power supply off HDMI works perfect when I connect the power supply, no signal.
please I really need some help.
