I have a TI-84 plus calculator I purchased in September. It does not power up anymore. I have changed out the 4 AAA batteries and still nothing happens. I shouldn't have to change out the back up battery should I? Bob

My i-mate does not start


Hello

you just made a "HimaClearJumpCode.exe" run on ur device(this file exists in ur upgrade folder),and now you are stuck in the bootloader mode

1-hard reset ur device(it wont boot,off course)...

2-plug it in the usb port,u should see that ur system has found a new hardware(if it doesn't,change the USB port)

3-now run the himaupgradeUt.exe.

If this does not work,

1-take the battery off device

2-leave ur device for 12hours without battery,so that backup battery drains...

3-put back the battery,recharge and enter the OS(this option wont work if u have erased the ROM)

4-rerun the upgrade...

The battery might be too low to be charged by the charger,if that is the case;

1) Remove the battery from the phone!
2) Take 3 fresh AAA batteries in series (total 3 x 1.5V = 4.5V)
3) Connect the (+) wire to (+) on the battery
4) Connect the (-) wire to (-) on the battery
5) Hold this in place for 60 seconds.
6) Put the battery in your phone
7) Switch on phone and start charging (via USB)

My AT&T Blackberry Curve does not charge anymore, is it the battery or the...


Hi.

Here a series of useful answers to common questions asked when an At&T Blackberry is not charging anymore.


2ca514a.jpg

1. My Blackberry is not charging anymore. Is it the battery or the charger?

Possible reasons are faulty battery, defective charger, bad contact on phone socket to charger.

When it is a charger problem, or a bad contact to charger, the phone will not detect that the battery charger is connected.

When the problem is the battery, usually you can see the charger beingdetected, and the charging line progressing, but the battery nevercharges.

The charger can also be tested using a Voltmeter. If the charge is in good working order, the Voltmeter will read a value within half volt from charger specifications.

2. Do batteries actually lose ability to work?

Yes they do, and the fault is not unusual.

3. How much will a new battery cost?

Most ordinary Li-Ion batteries for BB are sold at less than US$10. You can see a choice of sellers here: Blackberry Curve Battery
Ensure that the battery is compatible with your Blackberry model.

4. How much will a new charger cost?

Ensure that the charger is compatible with your Blackberry model.

5. Will AT&T service the phone?

They will do, providing that the phone is still under warranty. Newwireless devices like your BB carry a one-year warranty from date ofpurchase. Refurbished devices carry a ninety-day warranty from the dateof purchase. If the phone had been purchased in US, to make a warranty claim after the first 30 days from purchase, you can call At&T at1-800-801-1101.

If the phone warranty has expired, a good choice could be going to anAt&T licensed phone shop, and asking to test battery and chargeron the bench before buying a replacement battery.

Lifedrive won't power on


When you plug the unit into the wall to charge, poke the reset hole in the back of it at the same time. This should reset the internal recharging mechanism in the Palm. Let it sit for a couple of hours and then see if it will come on.

Casio E-100 didn't power up.


Try this Does the yellow light come on when you plug the charger in? If so, leave it charging for 2 hours, then do a hard reset while charger is still plugged in. I think, on E-100 it involves holding down Power button, while pressing reset button on the back of the unit with a stylus for a few seconds. Warning: you'll lose all your personal data on E-100 this way - but then again, it's probably lost already.
