Re: Bad design
My Dell laptop had the paint coming off the left shift key, resulting in a fairly bright keyboard backlight "spotlight".
I should have just taped it over, but warranty! So I had Dell fix it. Big mistake.
First time the guy came to exchange the keyboard. Afterwards, it felt a bit wobbly, but okay, maybe that's expected. Only that the thing bluescreened several times during the following week. Crash dumps were inconclusive. Once it even complained abot the hard sisk (M.2 SSD) gone missing and refused to boot, but recovered after a bit of prodding.
Back to IT it went, and I got a loaner. Their tests did not show anything wrong.
Dell came again, a scant two weeks belatedly, and fixed it again.
Turned out the keyboard was very loose, and the case screws were loose too - except the one that was missing altogether. Our IT guy tightened everything, and it has been stable for two weeks now.
My theory is that the technician, and I'm using that term loosely, did not tighten the screws sufficiently on the first visit, causing any slight warping of the case to slightly disconnect the SSD.
