IBM PS/2 P70

Does anyone have an IBM PS/2 P70?

The most expensive computer I ever bought.

Unfortunately it no longer boots up. When I power on the orange screen comes on, but it doesn't beep, no bios screen or anything.

In the past it would burst into life if i firmly slapped the sides before powering on, but that no longer works.

Any suggestions?

Is there an HMM for this system?

Found a video of a guy getting a PS/2 P70 up and running: https://www.youtube.com/watch?v=vRU7U1i2hCU

I've got one of these flapping about on the floor of my workshop. I'm just trying to summon up the energy to take a look at it....

Probably needs a complete recap; I've recapped all of my PS/2 machines (yeah, it takes awhile lol).

If a slap had previously worked, I'd check the ROM BIOS and see if perhaps it's creeped out of the socket a little and needs to be re-seated (since the BIOS also doesn't come up).

I'd also grab a multimeter and check the voltages going to the mainboard. (Also check Power_Good as well, as if that is not high, the motherboard will not come out of reset.)
