I'm not sure quite where to post this, so apologies if it's in the wrong forum.
As far as I can tell, the power cable on my Lenovo P50 has more-or-less conked out on me. It's one of the USB lookalike adapters. I purchased a replacement at Best Buy this afternoon (an Insignia 90W, for the record)
The replacement seems to be working, but my computer is giving me a song-and-dance about it not providing enough power. I call it a song-and-dance because I have had it plugged in for about the last 20 minutes, and it was holding at 80.43 watt-hours left. It has been holding at that level regardless of whether I take steps to maximize or minimize power usage. The output is 90 watts/19 volts (from what I can tell, the Lenovo unit is 20 volts instead of 19).
I'm reasonably convinced that Lenovo's software is having a temper tantrum but I am open to the possibility that the voltage is at issue (or that I simply got a bad unit). If it's Lenovo's software to blame, is there a workaround? If it's a bad unit, I can just return it and get a replacement. If it's a bad model, I can return it and specify what I need (though it would seem odd that Best Buy's unit isn't "fit for purpose"). Advice? Thanks.
