Pls 2 palm laser won't power on

In my experience, on PLS found several times the power button defective after few weeks/months (especially if You work in construction sites ).
The ultimate fix is new power button (not replace the old one!) in a convenient position. I have fix several PLS3:


Notice: if You open your PLS5, You have to break the lateral sticker and the warranty will be void!! Keep this in mind!!

Bye!

Likely it's dirty battery contacts. Clean the contacts on the battery tray, and the coil springs in the laser, and it should start.
If not open the laser, reinsert the battery tray with good batteries and test the voltage at the battery connector at the rear of the laser.
Check for signs of water damage or corrosion.
short out the power switch, to make sure it's not the problem.
The switch circuit board, power connectors, battery tray, and motors are the only electronic parts still available for these lasers, and that is only because they share them with the RL-H3A, which was only discontinued in 2011. If none of the above will make it turn on, you'd need to find used parts, and try and rebuild it.

the pls is a pendelum system you need to open it from the rear and shift the weight it is usually a set screw that you turn in or out to change the resting pointof the pendulem

It could be the battery. may be the charger is stuck ,did you Connect the E2 to the charger then soft reset ?this should reset the charging circuit on the Palm.after that Let it connected to the power adapter for a good 2 hours. After that, disconnect the Palm and see if it will turn on. If not, then you need to get a replacement battery for your Palm.hpe this helps.pls do let me know thanks

Is your Palm Centro device locked up and frozen. You might want to try a hard reset. Here’s how.

1. Remove the battery from the rear of the unit.

2. Hold down the power button while reinserting the battery.

3. When the second Palm logo appears, release the power button.

4. Press the Up button to complete the hard reset and erase all data on the Centro.

have you got the batteries in right?if it worked before you changed batteries,then the new batteries may have been put in wrong or the new batteries might not be any good.check

pls rate me fixya if i have fixed ur problem

There are a couple of things you can try.

1- Poke the hole in the back where it says reset.
This will in essence reboot your Palm.

2- Make sure the Auto-Off after: is set to 2 minutes by going into the Preferences, Power section.

3- If your Palm is not holding charge, connect the Palm to charge it. Turn the Palm on and make sure the battery at the top has a lightning bolt going through it. This will let you know it is charging. Then, push the reset hole in the back to reset the Palm. This should reset the charging mechanism in the Palm and allow your battery to hold power.

If the Palm does not hold power after step 3, you may need to see about getting it serviced.

If your Treo loops or freezes during a soft reset, a system reset may help. Performing a system reset allows you to get out of an endless loop in order to uninstall a third-party application causing the looping: 1. Press the Battery Door Release button and slide the battery door downward to remove it from your Treo. 2. While pressing and holding Up , use the tip of the stylus to gently press the reset button on the back of your Treo. 3. When the Palm Powered logo appears, release Up . 4. Delete the third-party application that you suspect is causing the problem. 5. Perform a soft reset. The wireless features of your phone are not available until you complete this step. Good luck!
