Upgrading the soldered-on RAM of a Dell XPS13 7390 laptop
> So as a final step I fired up memtest86.<p>Doesn't Dell have a built-in hardware tester in the BIOS (press F12 for the one-time boot menu, then choose its option), complete with a memory tester? Or is that only on the more professional Latitude/Optiplex lines? The built-in tester would have the advantage of also testing other parts of the board.
