Well if you want my advice, this laptop came with a 80C86 (9.54/4.77
MHz) and MS-DOS 3.3. And the symptoms sound just like the power
regulator board is bad. Which is really common for those old Toshibas.
If you can get 5 years out of one of these boards, you are doing well.
And good luck finding one of boards still working. I even searched on
eBay for years. They just don't exist anymore it seems like.
