Hi guys,
I am restoring a Toshiba PA7224E FDD and getting weird values on my 12V rail.
If I measure voltage on 12V on FDD connector without battery it shows ~15.3V. With a battery attached it is ~13.2V or something like that.
For 5V rail everything works fine as it is regulated by TL1451 chip. For 12V rail, I cannot figure out how it supposed to be regulated. So not sure if there is an issue with my FDD board or it is just designed like that.
I would really appreciate any help, or if someone has the same model and willing to measure voltage on 12V rail.
Thanks in advance,
Branko
