Sitting here and contemplating the pros and cons of digging in and doing the work that MAY fix a bunch of keyboard errors on a laptop or just parting the thing out to upgrade a new one with a few improvements*. . . On the one hand, replacing the keyboard MAY work (and be a less expensive option, discounting my work), but. . . involves—on this compy—almost complete disassembly (including mobo removal, which is a royal PITA.
So, $$ vs time and irritation. . . and no assurance of effecting a fix. Meanwhile, when kybd errors irritate me enough, external BT kybd to the rescue.
*Would need new one to use compatible RAM and have open slots; be able to accept an extra storage drive, for starters.
