Hi Lawrence: I expected a keyboard problem, since the owner said it had a stuck key. Sure enough, the boot screen would flash as if you were holding down an incorrect key. When I opened it up, the row and column flex connectors were plainly visible. Also, the keyboard pinout is in the tech ref (which is online, if you don't already have it). I peeled a corner of the flex circuit up off the aluminum plate, and could see metallization crossovers where the shorts likely exist. I could punch a hole at the crossover to break the short, but then I would need to jumper the cut traces. And this does not look like a solder job -- liquid conductive ink perhaps? There could be shorts in the middle of the key array too. The keyswitches are plastic, with posts that protrude through the mounting plate, and then melted into place. All in all a nasty thing to even think about repairing. Perhaps I am on the wrong track (no pun intended), but I pulled the two flex connectors out, so the ribbon cable is not connected -- I can measure many shorts right at the flex terminals. All of the melted-in-place keyswitches would need to be removed to asses the situation properly. Bummer. At least I have a new keyboard I can plug in. I have not opened that one up, so I don't know if it is different. gil ;----------------------------------------------------------- ; vaux electronics, inc. 480-354-5556 ; http://www.vauxelectronics.com (fax: 480-354-5558) ;-----------------------------------------------------------
