Alienware 15r3 Freeze and Battery
Good afternoon, help me understand the problem. Sometimes - once a day, sometimes - every few minutes the system on the Alienware 15R3 laptop is completely frozen. To be repaired by disconnecting the charging from the outlet (as soon as I take out the wire, everything works). I tried reinstalling. The driver installed after installing Windows and did not install at all, nothing has changed. The power plan also changed the effect of 0. Parallel installed ubuntu there are no such problems.
And also wanted to ask, is it normal that in 1.5 years the battery has degraded so much?
