Your Palm uses all SMD technology, including embedded devices in to the
circuit board. They don't do very much service at the board level. They
change the circuit board that is defective. There are only a few types of
components that they would change on the circuit board. After servicing,
they do any required calibration and updating of its firmware. As for you to
buy any parts for you Palm, they are proprietary. Palm will not sell service
parts to an unauthorised service person. This is the same for all of these
manufactures.

at RM380 or US$100 for the repair job, I might as well buy a new Palm
Zire 38 costing around RM500 US$131. plus the new Zire has MP3
playback which my M505 lacks.

Thanks

I think that's what JANA was saying between the lines.

Good suggestion. Before you do that check the output voltage of the
charger. The Motorola switching ones sold with that series are very easy
to "fry".

You don't need an official Palm one as long as the polarity and and
voltage (5 volts) is correct. I was able to replace one with the power
supply for a USB hub that cost far less than a new Palm brand charger.

Another thing to do is while the battery is disconected, put it back on
the charger and see if it boots. A bad battery will prevent that series
from turning on in the charger.

Unless you are 100% dependent upon the data in the Palm (no backup or
hotsync), You could try pressing the reset button with a paper clip and
then holding down the power button. If you see a "Powered by Palm"
message and the Palm logo on the screen, then it should be ok. When you
let go of the power button, you will be offered a choice of erasing all
memory or not.

If you don't need the data, select yes.

Batteries can be purchased complete with a screwdriver set for under $10
from eBay. Note that they are fastened to the screen with double sided
tape and need to be carefully pried up. I use a "case cracking" that
was part of a set of "cellphone tools". It also helps to open the Palms.

Remove the screws with a T5 (torx) screwdriver. Do not use any other size,
or try to force it with a different type of screwdriver. If you do, you
will end up with stripped screw heads. The only way to open them then
is to take a Dremel tool and CAREFULLY cut a slot in the head of the screw
so that you can open it with a slotted screwdriver. A very tricky procedure.

Start near the SD card socket on the top and carefully seperate the
top from the bottom. A fingernail will do if you don't have the correct tool.
The top will seperate with a loud "crack".

If you have any more questions, you will get a faster answer if you
email me.

Geoff.

I did the reset part with advice from palm support but still could not
power on my palm. just nothing happens. when charging, the on/off
button will emit greenish light (just like normal charging) but when
uncradle, the palm will emit a soft weak greenish light from the on/off
button. nothing happens When the on/off button is pressed. And there is
no more the beep sound when one cradles/uncradles the palm.

There definately is a problem with the charging circuit. The m505 and m515
use a lithium ion battery which has some circuity in it so it is possible
that replacing the battery will fix it.

Open it up and check for corrosion. If you find any, remove it with a
toothbrush. Be careful, the fluid inside a lithium ion battery is very
corosive. If it looks like the battery leaked (not likely, but possible),
carefully remove it, wrap it in plastic and dispose of it.

Unplug the battery and place it back on the cradle. If it turns on,
it's worth replacing the battery, It's not 100% that this will fix it,
but it's well worth a shot. If nothing happens, you need a new logic
board.

The best way to get one is from another m505 with a broken screen.
The logic board has two connectors on it. The screen connector just pops
in and out, with the unit open you cannot miss it. The battery connector
is the other one. It slides in and out of a socket on the logic board.

Yes. the m500's (m505 and m515) will work on the cradle without a
battery in them. This is a good way to determine if the battery
is causing a problem.


thanks for your advise.


You're welcome, good luck.

Geoff.
