Small company here. I have a few laptop power adapters that do not work. The bad adapters were swaped out with working adapters and/or the laptops we have on reserve for employees just aren't paired w/ adapters. We have all Dell desktops and notebooks. I'm now tasked with seeing what we can do to get replacement working AC adaptors.
I can't imagine Dell would be able to match AC adapters to laptops to check on warranties?
(Yes, making a note of what didn't work and filing a warranty replacement at the time things broke would have been better.)
