Marcel, my son managed to break the eject button/lever off the PCMCIA slot. I use it a lot when travelling - I have a PCMCIA adapter for my compact flash cards for my camera which is much neater (a little bigger than a credit card) and smaller than a USB card reader like I use with my G5. One thing that annoys me about the new MacBook Pros is that they use the Express Card 34, which is too small to use for a CF card adapter; the only card readers available are for other formats which are smaller than the CF card. I keep hoping they'll see the light and include an Express Card 54 with the next version...not that anyone seems to have made a CF reader/adapter for them either yet. (May have to just get another FW/USB 2.0 reader!)
As for the PCMCIA slot - no eject button = no ability to use the thing, since I wouldn't be able to get the CF card out of the adapter! The replacement cage was all of $19 - I hate to think what they'd charge to install it, since it really means dissassembling the entire Powerbook!
I got it all back together and discovered that the DVD drive really wasn't working - it must have broken in the fall that broke the hinges and I forgot to test it. The hinges I had replaced by PowerBookMedic.com - that required removing the display and playing with glue; not something I really wanted to try and potentially screw up!
So...had to overnight a drive from NewEgg (the nice new dual-layer Pioneer) since I'm leaving on vacation soon and installed that today, which thankfully didn't require anywhere near as much dissassembly!! Put it all back together and had a momentary panic attack when it made the required noises but had no video. Took it back to the dining room table and discovered I'd managed to forget to put the display cable back in! Whew!
I HOPE that this will keep this Ti going for a while now - it's been an expensive little beast over the last year, (though mostly due to damage inflicted by a less-than-careful 14-year old who is no longer allowed to use it anywhere but the dining room table) - the hard drive died a month after the 3-yr warranty was up last summer.
