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?

 

Thanks

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

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.

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:

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.

Actually, it can still be the PSU.. Anything can fault a computer ;)

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!

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?.

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 :D

 

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 :)

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

    • Valve finally confirms Steam Machine prices, starts at $1049 for 512GB option

      By LoneWolfSL · Posted

      Valve finally confirms Steam Machine prices, starts at $1049 for 512GB option by Pulasthi Ariyasinghe The $1,428 option The Steam Hardware lineup that Valve announced last year is slowly starting to roll out. Following the recent Steam Controller launch, Valve has now confirmed the price of the Steam Machine, its all-in-one console-like solution for PC gaming in the living room. There are currently four variants being presented, with only the storage and the included controller being the biggest differences. All of the Steam Machines have the same internals consisting of a semi-custom AMD Zen 4 CPU with six cores and 12 threads, an RDNA 3 28CU GPU, 16GB of DDR5 memory, and 8GB of GDDR6 VRAM, all inside the familiar box Valve has been showing off for months now. The Steam Machine base model starts at $1,049. This has a 512GB NVMe SSD but does not come with a Steam Controller. Keep in mind that storage can be expanded with the microSD card slot too. Next, the $1,128 model has the exact same storage as the previous one but it does come with the new Steam Controller. If you need the Steam Machine to have more storage for games and apps than that, then the 2TB tiers are also available. The $1,349 Steam Machine has no controller once again, but it does ship with two extra faceplates (red fabric and solid walnut) to replace the standard black one. The final option costs $1,428, and it adds the controller back into the bundle. The Steam Machine ships with the Linux-based SteamOS. The box has a 1 Gigabit Ethernet port, DisplayPort 1.4, and HDMI 2.0, as well as one USB-C and four USB-A ports. Keep in mind that when purchasing standalone, the Steam Controller has a $100 price tag. With the above bundles, that drops to $80. It's a rather expensive machine for the internals it is touting, though the design and small form factor do help it somewhat. However, at the same time, the lack of upgradability hurts it. Valve says the ongoing parts shortages and massive price hikes for memory were the leading causes for this price. "The overall effect is that our original goal for the price of Steam Machine is no longer viable," added the company. "So the prices we're sharing today reflect the state of the world for manufacturing; or, more accurately, it reflects the price of the components as we've secured them over the past 6 months." Valve wants interested gamers to reserve it now to get the chance to pre-order a Steam Machine starting June 25, with shipping starting on June 29. Head here to sign up. The invites to buy it will be sent in a randomized order.

      What the press release doesn’t mention, however, is how much water the natural gas plant itself will consume, Natural gas plants use about 2,803 gallons of water per megawatt-hour produced, which is significantly less than coal-fired plants that use around 19,185 gallons per megawatt-hour. Overall, natural gas plants are more water-efficient, using 584% less water than traditional power plants on average. AI generated
