    Same thing, but my keys are all messed up, so when I enter a 5, then a load of asterisks pop up on the screen

    Will turn on - blinking cursor - no other keys work - recognized by TI connect

    So the calculator has 5 columns of buttons, and only my FAR LEFT column doesn't work (with the exception of the On/Off and 2nd keys) So everything above the On/Off key and below the 2nd key in the far left column don't work. I have no idea what is wrong and water damage seems almost impossible because I have no idea when it has ever even come in contact with water.

I found a solution to my problem. I think water got into my I/O port and it shorted it. The way to fix it was to blow really hard into the I/O port or use compresed air.

try unhooking you're positive battery cable wile the car is running then turn ignition off and put positive cable back on. if the problem is electrical this should reset it. could also be a fuse or a splayed wire.

Logitech keyboard,s keys are not working


Modern keypads arent as great as old ones where each key had its own switch and you could just open and fix it. new keypads have everything interconnected inside them. The only thing to do is buy a replacement, But if you really love this one keypad, you could try and clean it out with a blower and make sure the keys that are failing arent failing because of dust or unwanted debri.

Sound work with Headset but on speaker no sound otherwise


one way what u can try is have your headset when u turn on the psp after switching off. then once again try restarting without it. now u might have sound if your speakers arent dead. else am sure ur speakers or connection to it is dead. else try wit different UMDs. again one more is try updating the psp to a newer version. if u have a software problem which causes the sound off then that might fix it.

Creative Zen Vision M frozen on the start up screen


Hey guys, I've had the same problem for over 2 years. Guess what? I fixed it today!! It is indeed a hard drive issue. I recommend following a guide to disassemble your zen. (Remember, this is only if you dont have any other choice) When you disconnect your hard drive, plug it right back in there pushing hard on it to make sure it is connected completely. IF that does not work, this is the final resort.

I did this and it worked. Normally you arent supposed to ever do this to any kind of hard drive. But why not? since it is already broken. lightlyish hit it a few times, and take the end of a screw driver and stick it in the hole on the end of the hd and pry it loose a tad. you arent trying to pop it open, just givve it a little breathing room. Worked for me, normally it shouldnt. But no one seems to be sharing anything so hopefully this helps someone some time in the future.
