Treo 650 buttons not responding from stdby

[luigi966]

An odd problem with my Treo 650 today... Every once in a while, it acts as if the entire keypad is dead.

I hit the "end" button to bring it out of standby, and the screen lights up as normal, with the "keypad locked" indicator as is appropriate. But no matter what button I press, I can't get out of the keypad lock! What's more, that indicator doesn't even come up again when I press the wrong key - the way it normally would (it DOES respond normally to the touchscreen... but it's locked of course, so I can't do anything). In fact, it acts as if the keypad is dead entirely. Hitting the "end" button won't even turn it off again... I have to wait for it to time out.

I know that it hasn't frozen because it still responds to the touchscreen or the insertion of an SD card normally (for a keylocked palm). I don't think it's a hardware problem, because it wakes up as usual with the "end", "datebook" or "mail" buttons. It's only once it is awake that the keys stop responding.

The only visual evidence of the problem is a single pixel in the bottom right corner of the screen, blinking at about 1x/second.

This problem is intermittent, not solved by a soft reset, and completely unpredictable. I will be in the middle of a game of dopewars (), and realize that I can't type in numbers anymore, or access any of the hard keys. Twenty minutes later it will be fine again.

It seems to have locked up for good now; even hitting the hotsync button on the cable will just wake it up, display the "keypad locked" symbol and then put it back to sleep. I want to try a hard reset, but without a hotsync I'm still worried about lost data.

Has anyone ever encountered this problem before? My treo has been dropped a few times, but not for months... and it has never suffered any serious trauma.

Ideas? I am at a loss.

No effect. It even seemed to have trouble calibrating the touchscreen, accepting my language choice etc. It did eventually lay back and accept those inputs, but the moment it went into standby I was stuck in the same old boat.

I'll be contacting palm for an advanced warranty replacement. I can't live without my Treo!

Still interested in anyones' ideas....

Not sure of a solution, but do you have a screen protector installed? If so, I know that if it is under the corners, it can cause funky screen problems. If you have one installed, you might try removing it and checking to be sure there is no dirt under the edges of the screen.

I hope this helps.

Hello luigi966,

This is Kevin from Palm. Steve's right about removing the screen protector to see if that resolves the issue. And yes, you may have debris trapped under the edge of the screen. Use the corner of a piece of thin, stiff paper to very gently slide all around the edge of the screen. Don't let the corner of the paper travel more than an eighth of an inch under the screen edge frame. By doing this, you may be able to dislodge small particles of debris trapped under the frame.

Sincerely
Kevin
