I have a Beelink Mini S 8GB RAM and 500GB HD (MINISV1-A-8256SDOW64PRO-A).
Unfortunately it’s no longer under warranty but I’d really appreciate some guidance on the problem it’s been having:
Everything is working perfectly (with Windows10 or Linux) except when I try to reboot or switch it on before it has completely cooled down, which usually takes about 5 minutes.
If I try, it lights up the blue power LED, turns the cooling fan but doesn’t show any video.
If I don’t switch it off, it stays in this state permanently.
And when it’s like this, if I try to switch it off using the power button, it switches off the blue LED, stops the fan and seconds later switches on the LED again and turns the fan, but it’s still on the black screen. If I insist on switching it off using the button, it repeats the behaviour: it restarts and remains on the black screen. Then I have to remove the power supply and wait for it to cool down. Then it restarts normally.
What I’ve already done:
- Changed the thermal paste on the processor
- Cleaned the RAM contacts
- Removed the glue residue left by the backup battery that was stuck to the motherboard
- Checked the voltage of the backup battery (OK)
- Thoroughly sanitised the motherboard with isopropyl alcohol
- Checked and reset the BIOS configuration ((JTKT001 ×64 - 04/12/2022) via the CMOS reset button (10sec. without energy).
- Changed the monitor
- I’ve tried booting with ethernet, without connecting peripherals (keyboard, mouse)
What I’m thinking of doing:
- ?Reinstall the BIOS
- ?Reflow the processor
- ?Check the capacitors (this will be a bit difficult as the board will have cooled down by the time I remove it).
But I’d be very grateful if anyone could give me some advice.
