Follow the detailed instructions below on how to completely reset your RCA Android 7 Voyager (RCT6773W22) tablet.
Step 1. With your tablet off, press and hold the volume up (+) button and power button until you see the RCA splash screen with Nipper and Chipper. Release both buttons to reveal the Android bot on his back with a caution symbol above him.
Step 2. A new screen will appear asking you to use your volume up/down keys to move and the power button to select.
Step 3. Use the volume down (-) button to highlight "wipe data/factory reset." Once highlighted, select using the power button.
Step 4. A new screen will appear asking you to confirm your selection. Use your volume down (-) button to highlight "Yes -- delete all user data." Press the power button to select once highlighted.
Step 5. Once the tablet is finished wiping data, you may press the power button to select "reboot system now." This will restart your tablet.
Step 6. The system will begin to reboot and once again display the RCA logo with Nipper and Chipper. The next "Welcome" screen will prompt you to select your language of choice. Scroll through the options using your finger and press start when finished. Congratulations, you have successfully reset your RCA 7 Voyager tablet.

Reboot the entire system clear the virus

If it wont show anything then there may be a problem with the launcher( the program that loads all of your apps and widgets). If you cant get to the settings then consider having a tech professional look at it and dont touch anything if you have no clue what it does i've learned that the hard way.

Error codes are only of use by the Toshiba Technical staff and of no use to you as the consumer.

If you report that to the Toshiba Technical personnel, they can transcribe the error number for you.

If a blinking light comes on when charging, sometimes it indicates No Charge or the power cell inside the computer is not accepting a charge and will not function. You might replace the power battery if it has been in there for several years. They do tend to die after a while. As for the computer, it should operated without the battery. If it fails to boot when the power adapter is plugged in, then one of two issues are common. 1, the power adapter is faulty and needs replacement. 2. the computers CPU may be damaged by a power surge and that is bad news.

First, give the screen a good cleaning using a microfiber cloth. This may inadvertently remove the lines even though they are in the display.

If this doesn't work, you'll have to send the laptop back for repairs. Screens are not a component that can be replaced easily (such as RAM or a hard drive).

If your laptop is not under warranty, scope out some local computer shops that can replace the display for you. Make sure to ask them for a quote BEFORE they do work on your computer, otherwise they have the right to deny you your laptop, once they fix it, until you pay up (a possibly very nasty price).

buy usb dvd writer that include and cd driver / software, you can write anything on it.

It sounds like the system is trying to reduce power consumption to save battery life. Check your power settings in the control panel and set them to Max Performance to see if it stops doing it. If it does, you know that was the reason. If it doesn't let us know.

Good luck!

Hi,

The display properties indicate the hardware is working, so it's likely just a setting.

On HP/Compaq models you will see a picture, usually on the F4 key that looks like a screen with two lines beside it.

You need to hold down the Fn key(bottom left) and then push the F4 key at the same time to cycle between LCD, external or both.
If it is a newer model, a menu will pop up when you do this asking if you want to duplicate the LCD on the external, switch to the external or extend the desktop onto the external. Select the appropriate setting or continue holding down Fn while pressing F4 to cycle between the settings to the one you want.

If you have re-installed the computer at some point with anything other than the factory recovery set this may not work and I will have to give you a longer set of instructions.

If this works please rate this as fixed, if not reply back and indicate what version of windows you're using and I will post the instructions for the "long" way.

1. At the BIOS password prompt ("PASSWORD = "), press and release the following keys, one after another:
Ctrl, Tab, Ctrl, Enter
The computer's response should be:
PC Serial No.= XXXXXXXXX
Challenge Code= XXXXX XXXXX XXXXX XXXXX XXXXX
Response Code=

2. Get response code from your local toshiba support center
Then follow the instructions the support guy will give you to unlock the laptop

check you manual or with toshiba, but it is possible to get the bios reset you just need to have the right tools. It might be a disk or a setting in the bios itself.
