I frown on Dell for three reasons:
Modern Inspiron:
Your battery is not working properly. Please see the nearest Dell support center for details (It was fine, all I did was reboot the darned thing!)
Dell SupportAssist on all in one PC, claiming my HDD is bad (it's not, and I can still boot Linux via the other boot partition, run scans, SMART tests fine!) It only does this on the Windows side, and trying to skip or end the check just turns the PC off. It refuses to boot without SupportAssist telling me that my drive is bad when in fact it's clearly not.
Dell Latitude CPi and Dell Latitude D610: "1-3-5" battery error code. This was an extremely controversial one at the time since it's based on planned obsolescence and from the 'laptop fire' scandal that HP had at the time. After a chip inside the battery pack counts 500 recharge cycles. it burns a pico fuse inside the board of the battery and the LED that shows the charge status on the battery pack (CPi) or the charge status (D610) flash 1 time, pause, 3 times, pause, 5 times and the cycle repeats. Dell says it's a 'replace battery' error. Sorry, but I don't accept replacing a perfectly fine pack because y'all scared of them exploding. Unlike most folks I'm not an idiot and take care of my things. This pico fuse is surface mount, and there was a 150+ page thread that's no longer available online (the forum is gone) and despite some claiming to attempt to replace the fuse, the chip still sees 500 recharge cycles and just burns the fuse again and again. Today, modern dell laptops will just display a battery icon in Windows with an ! inside it after the same recharge cycle count, today, meaning you have to replace the computer because it's non-removable. Dell never learned their lesson.
