Really good advice. I managed to open my 33C this way.
Inside was a mess, the flat sheet with traces linking the battery terminals to the internal PSU was baddly corroded.
The trace corresponding to the (+) charging terminal was broken, but this is not a problem as I am charging the batteries externally, but the pad of the (+) supply did not make reliable contact; this is the end point of the flex connector sheet that makes contact with the keyboard assembly.
I cleaned the contacts, but both sides (the flex side and the keyboard assembly side had dark patches from the corrosion).
In the end I stole a bit of foam from the keyboard assembly and inserted it under the flex connector sheet on the PSU side. This increased the pressure with which the flex sheet is pressed against the keyboard assembly, finally making reliable contact.
BTW my 33C is the old style with the unsoldered ICs.
