I took my Treo 755P apart to dry it and upon putting it back together a pencil eraser sized black molded rubber like part with two gold electroids on one side appeared left over. I can't locate where it goes?

takie out the batters then put them back in.

When you see the first screen (the orange one) hold the UP button as the bar moves across the bottom of the screen. Let go right before the screen goes to the silver logo. If it continues and opens Prefs, then you need to delete the program causing it to reboot. If that doesn't work, do a Hard Reset. A Hard Reset will erase everything on your Treo, so only do it if you have to. Google how to and it will work perfect.

Hard Reset Palm Treo 755p or 700pPalmTreo 755p or 700p.
1. Disconnect the Treo from a charger or USB cable.
2. Remove the battery cover and take out the battery.
3. Press and hold Power/Endwhile you insert the battery.
4. When the screen lights up with the logo appears, releasePower/End.
5. Press Up when the Erase all data? prompt appears.
6. Press Up to confirm the hard reset.
7. Go through the steps of setting up the device again by picking a language and calibrating the stylus.
Now your Treo 755p/700p is hard reset. you should have your info on a folder on your computer. hope this helps.

This procedure shouldn't be attempted unless you are resigned to the POSSIBILITY of messing your phone up.
When you say speaker, I am assuming you mean the audio speaker used when playing music, which is found on the back of the device, and not the speaker found in the earpiece.
The take apart should be simple but it is a bit complicated. Remove your back panel, then the battery and SIM and/or memory card if it has either. Also, remove the stylus.
With a small and special T5 screwdriver, remove the screws found underneath the stylus, and under the rubber stopper opposite of the stylus.
Now, you need to use a soft pry tool to remove the top half of the back panel by gently sliding it into the grooves that were hidden by the battery door.
Once removed, you should have access to the speaker. Replacement is just a matter of splicing the red and black wire together.
Reassemble in opposite order.
I hope this helps! Let me know if you need any more details.

in order to perform a hard reset, you take out the battery. hold the power button and insert the battery.

release the power button when you got palm/access powered. it should prompt you to erase all data. press up to erase and finish setting the device. no need to reinstall the palm desktop software.

NEED TO DO A HARD RESET ITS GOING TO ERASE EVERYTHING AND ITS GOING TO GET RID OF THOOSE PROBLEMS! JUST PRESS AND HOLD THE RED END BOTTON AND AT THE SAME TIME PULL THE BATTERY (KEEP UR FIGURE ON THE RED END KEY) THEN PUT THE BATTERY BACK, AND IF I WERE U I WOULD DO A SYNC EVERY WEEKEND!

the only way to unlock the device is to do a hard reset but it will erase all the info in the device :\

Dhorner64 is incorrect. Your phone is not fried if you are in a restart loop. You need to do a "warm reset" which will not erase data. It is the equivalent of doing a safe boot in Windows. Remove the battery from your 755p, then put it back while holding the up button on the 5-way. Hold the up button as the phone starts. I had to do this frequently, then run the DataViz Tech app, which is available free from DataViz, to fix their prefs file, which was the source of my crashes. The problem was solved by upgrading to Docs2go v11. I was reluctant to pay to upgrade a crashing app, but the upgrade ended the frequent crashes. I have not had a couple resets since upgrading Docs2go, and no reset loops.

Did you poke the reset hole in the back of the palm? This does a reboot.
You can try that, or try plugging it in to charge and while it's charging poke the reset hole (this is supposed to reset the charging mechanism).
