My palm freeze and the screen don't display.and sometimes it run slowly and turnoff

Original disc is probably not compatable with Win 7. Check out
Palm Support Palm Tungsten E2 Palm Desktop 6 2 and HotSync Manager... for newer software that MIGHT work.

The main problem these days are that people are putting windows 7 on desktops and laptops that are 4 to 6 years old. They don't have the video card that is capable nor fast enough to care that OS. So go back to the system it came with and the problem will go away, or buy a newer computer.

Have you added any new apps recently? Thats the usual suspect for this. If you can remember which one try taking it out and see if it behaves then.

It can be also from something as simple as running out of ram or space. Some apps don't handle this well and you get lockups or temp freezes. And sometimes this results in corrupted files which cause it to happen or other problems. Delete anything you don;t use anymore and that will help. Doing a hard reset and then restoring your files usually fixes anything else.

It is rarely hardware related. You would see a lot of slow operation, and probably it would run warm or hot. Usually if its hardware they just stop.

1.Bought Palm centro with freezing up problem then returned and got another one.
2. Second Palm centro again with freezing up with additional screen flickering problem....buy one problem take another problem....good huh? buy one take one..

3. Third Palm centro after returning the second, now I stil have and inherited the freezing up problem .....you always inherit the freezing up problem even as many times as you changed your PALM CENTRO.

conclusion:

I WILL NEVER BUY PALM CELLPHONE AGAIN.
I WILL NEVER BUY PALM CELLPHONE AGAIN.
I WILL NEVER BUY PALM CELLPHONE AGAIN.
I WILL NEVER BUY PALM CELLPHONE AGAIN.
I WILL NEVER BUY PALM CELLPHONE AGAIN.

try clearing up your web history, sms, or unwanted software....on the browser, click on blazer top left corner, click on history and clear all..tested if it doesnt work back up your phone and perform a master reset

My Centro doesn't respond ("freeze") on incoming calls up to 10 times a day. The "answer" button (on the screen) and green "send" button (next to "phone") block and it is impossible to accept the incoming calls. It is necessary to perform a soft reset to solve the problem temporary. Even after hard reset the situation is the same. This is very frustrating for a new device. Sometimes, frequent callibration of the screen from the "Preferences" menue delays the freezing effect. AFAIK the problem is software-related, considering the recovery after reset. Is there any update on the palm support page / forums, related to the problem? I couldn't find any. From time to time, there is onother problem I experienced - from the contact menu it is difficult to dial the selected number. Sometimes it is necessary to press “dial” several times resulting in significant delay.

i suspect a possible loose contact between the ribbon connecting the motherboard module to the LCD display module. if you can open up the laptop, check if the both the ends are snug and tight.

Upside down or just sideways? There is a "rotate" button on the bottom of the screen that allows you to go from landscape to portrait mode.

It sounds like your hard drive is crashing. You should run diagnostics. You can find out what manufacture makes your hardrive by looking at the label. It appears to me that the harddrive is accessible through a door on the bottom of the laptop underneath where your right palm would sit if you were typing. There are harddrive diagnostics listed by manufacturer at the URL below. http://www.tacktech.com/display.cfm?ttid=287 If the harddrive test fails you should replace the harddrive. Andy TechSack.com
