TheElite Posted August 8, 2020 Share Posted August 8, 2020 Hi all I've had this computer for a few months. Bought it second hand. Ran good all this time but yesterday I left it on while it was running a few tasks and when I came back a few hours later it was off. Tried turning it on but no sound or light. Tried a different mains outlet and power cable too. Still nothing. Any ideas?

Brandon H Supervisor Posted August 8, 2020 Supervisor Share Posted August 8, 2020 no lights or anything could point to the PSU going out. If you have another PSU try swapping it out or you could stop by a local computer shop to have the PSU tested as well Link to comment https://www.neowin.net/forum/topic/1398764-my-fujitsu-esprimo-q920-mini-pc-turned-off-and-doesnt-boot-now/#findComment-598571799 Share on other sites More sharing options...
Mindovermaster Global Moderator Posted August 9, 2020 Global Moderator Share Posted August 9, 2020 I don't think he can replace the PSU... Now, this seems like an old laptop problem. You need to resoder the power outlet to the PC. I've seen this many times in laptops, mini computers are no different.

Thanks Look on YT, there are over 100 tuts on "how to resolder power plug laptop" And there's several ways to do it. Your mini-pc is no different than a laptop. This for example: TheElite 1 Share Link to comment https://www.neowin.net/forum/topic/1398764-my-fujitsu-esprimo-q920-mini-pc-turned-off-and-doesnt-boot-now/#findComment-598571843 Share on other sites More sharing options...
TheElite Posted August 9, 2020 Author Share Posted August 9, 2020 Mine is actually an "eight plug" but I'll see how it goes.

PB73 Posted May 25, 2021 Share Posted May 25, 2021 If the Fujitsu Esprimo Q920 or Q520 doesn't turn on at all - appears totally dead, no noise whatsoever... then it's normally the CMOS battery which is dead. You just need to work out how to open the thing and replace the CMOS battery. Note that the power supply is built-in to the main board and is unlikely to be the problem.

Umm, if the BIOS battery was bad, it wouldn't save any settings, not fails to run. 1 hour ago, PB73 said: Note that the power supply is built-in to the main board and is unlikely to be the problem. Actually, it can still be the PSU..

TheElite Posted May 29, 2021 Author Share Posted May 29, 2021 Thanks both of you. The computer is still in my cupboard unfortunately, but seeing that working from home may still be in my future, and working from the sofa on the laptop is giving me back problems, I will be taking the computer to a repair shop to see if they can get it fixed. Thanks again!

FQ9 Posted September 12, 2021 Share Posted September 12, 2021 Hi. did you repair it? i got 3 of these,same problem,suddenly just shut down and wont turn on. replaced the CMOS battery,measured with multimeter, the PSU got power 220v in/20v out (near the power button there is 2 test points + and - ). one thing i've noticed,no clicking sound,maybe its the relay failure?.

ImMajesticAf Posted February 21, 2022 Share Posted February 21, 2022 (edited) Just saw this thread while trying to find an old page i used to fix some Esprimo Q510 (the following method states it was for q910/920/930 too!) I had about a dozen come my way at my local school because there was some sort of power surge or something iirc, basically all the internal PSU's died, and i found this page to bring some life back to them, you can bypass the internal psu and potentially revive the computer below is what I followed, but incase you don't wish to check it, you need to dismantle the pc to the point you can remove the plastic shield over the internal psu, in the computer, there are 2 solder pads towards and you can supply upto 20vthrough them according to the site, i personally used 19v, and there is a diode you need to remove, I can't recall if i removed the diode, or scraped away the trace to it (requires a lot of dismantling to get to) but I'll supply the same images from the site https://www.dkia.at/en/node/174 Hope this helps someone else in salvaging these neat lil PC's, i just needed to remember the voltage to revive my minecraft server aha Link to comment https://www.neowin.net/forum/topic/1398764-my-fujitsu-esprimo-q920-mini-pc-turned-off-and-doesnt-boot-now/#findComment-598713575 Share on other sites More sharing options...
SebastianRZSN Posted July 16, 2023 Share Posted July 16, 2023 Hello, I don't know if this post is active, but recently I got a Q520/k unit but it doesn't turn on, only when I hold down the power button it turns on a led and turns off quickly Link to comment https://www.neowin.net/forum/topic/1398764-my-fujitsu-esprimo-q920-mini-pc-turned-off-and-doesnt-boot-now/#findComment-598836018 Share on other sites More sharing options...
