I acquired a job-lot of these IBSWME v.1.0 boards; they were parted-out from the Lenovo IdeaCentre 300S-11IBR desktop PCs. Sold as "fully tested", yet none of the boards reaches POST.

No video output. Two beeps. Long pause. Two beeps. Repeat. Though the boards do detect when no RAM is present, by sounding one long beep then three short beeps.

A Chinese poster called 'yc630' provides some great information about these faulty boards. He posts his findings on the elvikom.pl and the chinafix.com forums. Apparently this is ultimately caused by a hardware fault with the N series ("Braswell") Pentium CPU.

yc630 writes:

"The reason for that is the BIOS can't communicate with the onboard SIO/EC, IT8618E, which is responsible for reporting the fan speed back to the BIOS. The primary reason of the communication failure was a result of the degraded LPC bus, especially the LPC CLK."

Hmm.. It seems Lenovo was aware of this fault for a long time, but kept it under wraps.

That insightful poster yc630 offers a fix of sorts. Using a 150 ohm resistor to pull-up the LPC CLK line. Though apparently this only works "if the LPC bus hasn't degraded too much".

I will test it myself and report back.

Just to report the problem persists; as suggested, the 150ohm pull-up resistor was strapped to the LPC CLK line, but made no difference. The board still repeatedly sounds two beeps, and video remains dead.

Another thread by poster yc630 is more optimistic. He/she eventually recovered the IBSWME board by reflashing the BIOS after it stopped booting. Though there are several board variants and different BIOS revisions which apparently are not compatible with each other.

Useful info,thanks.

The bios could be different depending on the machine type.If you want to try a bios post your backup and the serial number on the case
