Good day all. Newbie here and my first POST. Need some assistance. I have an ASUS LT that is six months old. Began getting Kernel-Power errors event id 41, Task 63. Part of the 'FIX' is to check the power supply. I plugged in the19vDC power brick and without a load on the brick, my meter read 18.6vDC. Logically thinking, one would think that the output voltage would be MORE than 19vDC since there is no load. Is there an acceptable threshold for the brick, +/- vDC? Do I need to replace the brick?
