The Fujitsu Lifebooks were legendary for their robustness back in the day, I'm genuinely sad you had that experience.

The only fujitsu laptops I used was back in 2011- it was a budget version for on-call and it was fine..

Sounds like the fans running 100% probably contributed significantly to the issue here. If I had to guess it was likely that the C-States were disabled in BIOS somehow so the CPU clock was running at full tilt the whole time, maybe combined with a bad thermal paste job.

I'm not here to defend Fujitsu but I've had really bad experiences with basically every major laptop brand (Dell: majorly bad coil whine and especially faulty soldered RAM, HP: keys vanishing from the keyboard and very weak hinges that break all the time, Apple: The GPU unsoldering itself and the butterfly keyboard shenanigans).

I don't really know any brand with a flawless track record sadly.

Before anyone brings up Thinkpads, they're trading on a reputation that hasn't been true for over a decade. If you have fond memories of a thinkpad it's most likely that you had it from before 2016, or it's "fine", but certainly not great.

Their consumer electronics arm is completely unrelated and also majority owned by Lenovo

Someone high up at Fujitsu is obsessed with making excessively miniaturized laptops. I once had an online fight on whether it's safe to run laptops closed, and realized that only Fujitsu manuals explicitly states that the machine uses keyboard top surfaces as a heatsink and running closed for extended periods is neither safe nor covered by warranty. IIRC Panasonic ones did say similar, but mostly towards noting that it ain't a server. Theirs were also one of the few that didn't seem to have been tested for Jack Bauer subset of MIL-STD-810 criteria, like thrown into a black SUV and flown somewhere in Middle East on a C-5 then C-130 then UH-60 and all the way back to the local soccer field.

Reaching further back, the Sylistic line was mostly quite good/durable, and I still use my Stylstic ST-4110 when I need to use an old scanner or control a CNC machine on my back deck when cutting tropical hardwoods.

Really miss the transflective display and wish that there were newer devices with such technology

I just have Fujitsu Lifebooks at Home since 2007. I think they are good, came with a bloat free Windows. I bought even one for my Mom over 10 years ago. I just changed once the HDD with a SSD. Now all my Lifebook run with Linux just flawless.

What year? The ones I had were the best. Very expensive, but service at the office & at home, very sturdy, very long battery life. That was somewhere early 2000s.
