Hello, it sounds like your contrast needs adjusting. Turn your calculator on; press the "2nd" key and down. The contrast should adjust.
Happy calculating

Laptop black screen


You turned on your laptop and horrors upon horrors, the screen is BLACK! You see that the laptop has power but besides that nothing is happening.
I want you to know that there is a very good chance you can get out of this situation quickly and without any cost. This fix works on all brands of laptops:


• 1) TAKE OUT YOUR LAPTOP BATTERY
• 2) REMOVE YOUR AC ADAPTOR CORD, that's the wall power, remove it.
• 3) NOW HOLD DOWN THE POWER BUTTON FOR 30 SECONDS
That will drain any static electricity that has built up on your laptop system board and many times fixes the problem of a black screen.
After the 30 seconds re-connect your laptop to the wall power and hit the power button normally and see if the laptop comes back up.
Replace your battery.
or if wont start
Here are the fix steps:
1. Turn off your computer
2. Disconnect every wire from it (including power)
3. Disconnect the battery from the bottom of the computer.
There will be two tabs labeled 1 and 2.
4. Re-plug in the power wire. (the battery should not be in the computer)
5. Turn on the power. The screen will work. Choose start windows normally. (if you get that screen)
6. Go to Control Panel -> (Mobile PC) -> Power Options -> Under Balanced choose change plan settings
7. Choose Change advanced power settings
8. Find Processor power management and change the minimum processor state from 5% to 100% for each On battery and Plugged in.
9. Click Apply then OK
10. Shut down you computer.
11. Disconnect the power cord.
12. Re-install the battery on the bottom of the laptop, plug in the power cord, and restart the computer.

Hi, my polar ft80 (black screen, white numbers), stops working quite often. The screen turns black and when it comes back, i have to go through the settings screens again. It happens about once or twice...


probably there's a problem with the connection of the battery of your watch, that's why it turns off, second it might have a different size of battery that have been installed. or the battery is not properly installed. these are all the possible cause of your watch. i hope i had been helped you.

My TI-86 has a completely black background, please let me know how to fix it. thanks


Hi,
After changing the batteries the calculator is restored to factory defaults, but the screen contrast may change. In your case (even if you did not just change batteries) the screen may be too dark. Lighten it a bit.
Press [2nd] key and release it.
Press and hold [DownArrow] until screen is light enough.

Hope it helps.
Thank You for using FixYa and for rating the solution.

Screen fully black


Black-Screen/Black-Pixel Fix for TI-Calculator

This will erase all memory and reset defaults.

1. Remove 1 AAA Battery
2. Press and Hold 'ON' for 30 seconds
3. Replace AAA Battery
4. Adjust Contrast to appropriate level

If this fails, try again with ALL Batteries removed including
the backup Lithium Battery.

If all else fails, try the following reset procedure:

1. Remove ALL Batteries (inc. Backup)
2. Let Calculator sit with no batteries for 2~4 hours.
3. Hold 'ON' for 30 seconds.
4. Replace all the batteries (May be good idea to use new batteries
just in case old ones were dead)
5. Turn on Calculator
6. Change Contrast to appropriate level

- Remember to use correct batteries or calculator may not work. The
correct batteries are Alkaline, Rechargable Batteries are TOO WEAK,
Heavy Duty batteries are TOO STRONG.
