Minis Forum UM690 mini PC - no power, board repair - This looks like a small beautiful mini PC

Nice repair and saving the customer's pc.

It would've been nice if you'd replaced that cap, it was right next to a power supply. In the future that PSU may fail. Probing with an oscilloscope on a PSU input without the input cap mounted you can observe big voltage spikes like 5v in magnitude. (depends on PSU PWM frequency). Those spikes are attenuated fast on the rail after a distance of 3-4cm of cooper track but it will harm that local PSU, or analog audio amplifier if is somewhere near by. Having an oscilloscope can make you understand that no cap is on a board for no reason.

Thank you very much our teacher SORIN. thank you for all

[wernerpaulin]

Sorin, thank you for the video! Can you please share the exact types of the replaced components? Thx!!

[aseidinfo]

It's a really capable light gaming machine too.
Great video!

Nu trebuie inlocuit si condensatorul mic?

The noisy fan is at the top part haha
I'm a fan of passive cooling, airjets, and big silent fans.
Modding is always an option, until manufacturers catch up and technology gets even more efficient and advanced.
Manufacturers usually always make it smaller, so that it makes either noise and/or thermal throttles, instead of just using a decent oversized heat sink and fan...
This makes more sense for a laptop, but for a mini PC? It's still about cutting costs. Silence lovers are forgotten.

❤I love this man, your very interesting, and hard working, thanks for your hard work buddy 👍.

I admire your repair and diagnostic skills, but it bothers me that you never bother to replace fuses or capacitors.

[daveunbranded]

I bet you can game off that if you use the PCI card to a video card. Probably work fairly well

Okay so gaming can wear it out? I have one with eGPU setup, adapter through nvme2 SSD slot, extra PSU for the external AMD 6600xt. It is now having trouble starting up, may take a couple minutes of jiggling with the ac adapter

Thank uou fir this video, for mine just last night i noticed the 2nd HDMI port stopped working, the one futher away from power port, no signal 😢, please what can i do, i got this March this year

I need to replace that exact same mosfet. What part number do i need to buy?

[ctecrwp]

Removing a cap with hot a good sign, instead of snapping with tweezers, so lets hope to it back some caps

[Trustsimo]

Thank you, teacher, but those 1st 2nd mosfet are going to take me crazy, every time I say I understand them, and now, the mosfet is getting hot because it is good, and those 24V at the gate 😅

[Donnez]

How do you remove the board ive been trying to fix my pc but the power button doesnt work

[maheshjawahar]

Hi.. can you please provide the details of the MOSFET which was replaced

[konstantinnikitin]

Daaamn, I can't find out how to disassemble similar mini pc correctly. Came here to check it but this part is skipped and characterized as painful. Any tips?

[SamiTM]

Hi Sorin. I have an x60s and got a fan error, laptop turning on got picture... But I dont have original heatsink and fan because I destroyed them in a DIY project and its expensive to replace. Problem is I tried multiple fans from multiple laptops allingning the pins exactly with original. Coolers are working but still got that error and laptop shuts down. You think they have a chip on original cooler that communicates with the motherboard? Preventing me using other coolers?

My UM690 died the same way. Hoping Im still within warranty. Cant access any of my data. Frustrating
