After going through some Tom’s Hardware posts, it sounds like one of the B1 chips at that time was unable to do power saving modes? Maybe win 95 was incompatible with that?
Intel 386 microprocessors dated before April 1987 are known as B1 stepping
chips. These chips are known to introduce random math errors when performing
32-bit operations, thus making them incompatible with Windows 95.
I was also curious.

So I was wrong.
