I have a PB here with a P key not working. I've replaced the scissor mechanism but the problem is that the springy rubber nipple is damaged. When I press on the contact underneath, it does type Ps with apparent contentment.

I found a source at http://www.irithm.com/Mac.key.replacemen...

with pretty good instructions, but, while they can provide the nipple, they don't say how to install it. It appears to be glued onto the keyboard base. (ifixit only sells complete keyboards.)

Any suggestions?

Have done the following:

1. Disconnect, test peripheral devices and network cables. Made no difference.

2. Perform a Safe Boot. Would not perform a safe boot.

3. Reset the NVRAM/PRAM. Made no difference.

4. Start from your Mac OS X Install disc; use Disk Utility. Won't do it.

5. Check your cables and power source. Made no difference.

6. Remove third-party RAM and internal hardware. Made no difference.

7. Perform an Archive and Install installation of Mac OS X. Can't do it.

8. Perform an Erase and Install installation of Mac OS X as a last resort. Not willing to do that, because I really need a couple of things that are sitting on my hard drive.

Is there anything I can do to retrieve the information that I need from the hard drive?

After replacing the upper case, I left the battery out, and charged it overnight to make certain that the PRAM battery was charged. Machine booted fine, and I proceeded to do a clean install. I did a verify, found errors, attempted a repair and was informed DU could not repair the disk. I erased the disk instead, and verified. Told OK.

Installed 10.4 from system disk. Installation proceeded smoothly, but upon restart, all stalled at apple logo (gray apple, gray background).

No Peripheral devices.

Since then, I have tried

1. Swap Memory - no memory difference.

2. Reset the NVRAM/PRAM - no difference.

3. Safe Boot - did not respond to command

4. Verbose - did not respond to command

5. Start-up from os 9 or 10.3 won't respond to C command at startup.

6. Start-up from Data Rescue allows view of drive. Scan indicates 2000 ms seek times at several points.

7. Start-up from os 10.4. Profiler shows full RAM installed, POST last run 4/1/76 (sic) passed. Software Extensions does show Dependency Errors on IOAudioFamily for .iokit.IOUSBFamily, and .kernal.iokit. Airport card was not found. Disk passed verification. Repaired permissions w/o fault. Selected HD as start-up disk, shut down.

8. Removed Airport card.

9. Restarted. Ejected install disk.

Gray apple.

I don't have another Hard drive to swap, and am hesitant to invest in another in order to test faulty HD as hypothesis.

All suggestions are welcome!

I've searched the internet for possible fixes, other than installing another new keyboard. Any recommendations?

Thanks,

Suzanne

p.s. Most of the "t's" did not appear as I typed this, however, I went back and corrected them so this description could be read.

Thanks! I removed the "T" key as you suggested and found a kernel of "mystery lint", cleaned the area, and proceeded to do a test typing of "t's".

Hope your day was as great as my "T"-key cleaning results.

Seems so elementary--thanks!

preytell, how does one lubricate their TiPWRBKs' hinge??

a million thankyous and kisses.

Thanks all, I kinda suspected it was an inclosed jobby.

I did however do some more research..in my drawer

and discovered a magic universal lube called 'INOX',

didn't list contents but it's a non silicone dry lube spray.

Decided not to open up torx screws, too much trouble..

I applied it in and around with a thin straw

type spray adapter, worked it back and forth a bit,

wiped up the excess, and so far it seems ok,

no creaking or damage to report...yet. Will update if

anything bad happens after this experiment. Thanks!

If I do not run any application the will not lock at all, but as soon as start an supplication the PB locks-u again :-(

My HD is not dying it works just fine. The problem I believe is with something on the motherboard. The computer will boot but I can only use it for about 10 minutes. Then it locks-up. If I shut it down by pushing the power button until it powers off and restart the computer it comes on again for another 10 minutes.

As for cleaning the upper memory slot, I have already this as well as clean the edge of the memory module.

Thought there was a recall a very long time ago PB G4 Ti computers that had problem with their memory slots.

Does anyone remember this type of problem?

Side note: The repair guide specifies that a 4mm nut driver is required, but its only use is to assist in the removal of the PC Card cage.

Any clarification or assistance would be appreciated.

You show many hinges for G4 repair, but for G4 Titanium.

So, should I consider my Titanium not repairable or can I use another set of hinges (i.e.: G4 Aluminium for 15") and go on my own ?

Best regards,

L.T.
