Yesterday, another weird thing happend.
First, about my setup. I first purchased a surface dock for my brandnew SB2, then I realized, it is a waste of almost $180 when I decided to buy a Dell U2719DC display because with a single type-c cable from SB2 to Dell , it carries all the data I need for display as well as use Dell as a fantastic USB hub. The only missing thing was an ethernet port which I solved it buy using a TPlink UE300 and connect it to one of 4 USB ports on Dell.
Now I have SB2 connected to a Dell Display via type-C and I don't need to use AC Charger or S.Dock single cables works both ways, carries data and video from my SB2 to Dell, carries power from Dell to SB2.
But,
After 1,5 months of using my laptop actively with Dell display , yesterday, my computer suddenly died. Immediately powered-off without any warning or anything. After trying to restart it, it told me that my battery is 0. Wow! It was connected all the time for almost 2 months.
After a charging for like 10 minutes, windows booted (and ask me for repair bla.bla.) and when I checked the batteryies it was battery-0 which went to %0 while battery-1 was still %75. Question-1, how could this happend? I mean how can one of the batteries can go down to zero while other was still %75. For those who'r gonna ask about if my tablet was properly attached, yes it was. I was also using USB ports on the body on the computer for keyboard and mouse. And also, type-c is on the main body, I was using my Dell display which was constantly feeding my computer with power.
Question/comment 2: I installed lots of rubbish battery tools etc. none of them gave me what the "cmd powercfg /batteryreport" and in this report I was able to see everything except battery status of individual batteries, it was designed to generate a report for combined values of two batteries. What the hack? Microsoft, please improve the batteryreport feature to produce detailed report for each battery.
Question/problem 3: Since the last 2 updates, my laptop is not stable with : Graphic performance, USB-Mouse performance and most of all overall system performance most likely because of something going wrong with the batter management..
So my comment is that; this USB-mouse freezing problem is just the tip of the iceberg. In some systems, this bug or whatever reveals it self to the full and I'm one of the victims of this glitch and naturally expecting Microsoft to offer me a fix for this very expensive product for which I put my money and trust .
PS: it took me 2 minutes to fix some typo in this message because my SB2 does not allowing me to move the cursor in this text, I press right arrow and wait for 1 second for it to react. I want to cry
PS:Sorry for my English.
