Which switches? There are three!
You have the programmer/reset switches on the side. Then you have the battery swap switch sort buried in the back. When the battery cover is removed, it switches power to the 9v so you can swap the battery without losing settings.
The thing is, the Portable is sensitive to amperage and voltage. Even though it a 6 volt cell, you may want to bump it up to 6.5/7 volt. You do not need the 9v since it only works when the switch is up. So supply power at battery terminals (2 amp should work) and push that switch in.
Then try pressing ad holding both the programer/reset switches a few times. Then the space bar to boot. This works for me to get them going.
Odds are though, you need a re-cap of the mobo. I am sending mine out next week to Uniserver for that service since a clean working board is so rare.
