OK, a "client" brought a laptop for me to look at &/ or repair. It wouldn't power up. They had used an aftermarket power supply with adapters. Upon inspection and after looking up which adapter fit that particular laptop, I discovered that she had used the wrong adapter and ultimately fried the motherboard. She had given me the laptop, power supply & adapter. That "client" brought another laptop to me for me to troubleshoot & I wound up using that adapter for her current laptop. Now she claims she NEVER gave that to me & wants the stupid adapters back. What say y'all?
