Review on 90W AC Laptop Adapter Charger For HP Envy Touchsmart Sleekbook 15 17 M6 M7 Series; 12 Months Warranty - DJW 19.5V 4.62A [4.5Mm*3.0Mm] by Mike Hernandez

Used it for an hour and caused my mouse touchpad to go haywire. Unplugged it and the touchpad worked normally. Swapped the power cable (not power brick) and the touchpad worked normally. The power cord the brick came with is already in the trash!Only used it for an hour after opening so unsure on the longevity or overall performance of the adapter. Not off to a good start!Edit: Adapter itself sucks. Touchpad still going haywire when plugged into different power cord but still plugged into this brick. Returning.
