here's another #permacomputing salvage - a Lenovo #Thinkpad T490 rocking #Fedora #Linux. I got it with a "dead" screen, so even before it got to me started looking for cheap 14" FHD panels. after I got it and started testing with an external display, noticed during a restart that the screen showed eversoslight activity so grabbed my phone and shone light at it and... yepp, that's a flawless image, albeit without backlight.

the dude I got it from assured me a Very Serious Place told 'em the display is toast and that's why they're selling it, so didn't bother checking. but now, this warrants another look. first off, not only is this is a *touch* screen, it's a 400+ nit 8-bit one; was expecting the factory standards which are like 200ish 6-bit. so, looked up where the backlight fuse is and thankfully it's on the exposed side of the motherboard; had the same thing on a T480s, and that one was on the other side of the board. 2/
