X31 dead, does not power on

[oliversl]

Hi,
I have a X31 in the office, it does not power on. Its dead. It was working fine.

The same happened a few months ago and after letting without the baterry for couple of weeks it worked again.

I read about the 10 power button press and then a 30 seconds press. Does this make sense?

What else can I try?

BIOS Battery?

Many thanks
Oliver

BIOS battery might be a problem. If you can pull it out and measure the voltage it should be 3V or a little bit more. Assuming it's the original battery, it's due for replacement as they tend to last about 7 to 10 years.

However, my suggestion would be to pull the MiniPCI card out of the system and see if it powers up consistently. In the past I have seen "power" problems in A3x and T2x systems caused by defective MiniPCI cards.

Sorry to revive this old thread. 2016 does not seems to old anyway!
My X31 is also, currently, dead. He does that from time to time, but this time, I'm unable to bring it back.

What happens: Plugging the power cord just gives a blinking green battery led. long ON and very rapidly OFF.

I have already tried the Power Button trick (10 presses + long press) without power cord and battery. Several times.

CR32 battery was low: 2.7v. I have already changed it to a brand new Duracell one: 3.3v (measured directly at the motherboard BTW).

I have already tried to blow hot air on it.

I know about "dead motherboard", but... Anyone knows something else I can try? Im good in disassembly, reassembly, changing thermal paste, cleaning. I have a multimeter. I'm no Chuck Norris with a soldering iron, but I might be able to reheat/resolder something that's not BGA. I also have a heatgun...

Any help would be appreciated.

Well... no replies! Thank you community!

I tried one more thing. I left the battery @ the freezer for ~20 minutes.
Then, reinserted it and charged it a little bit.
It was able to boot. Not sure for how long, but it booted.

Title's misleading.
