This sounds to be the screen. It's possible that the screen inverter has gone out, but usually you will barely be able to see the desk. Try plugging into an external monitor. If the external works properly. Then the problem is with your screen.

Remove the battery and power source. Remove the RAM and hdd. Power up with the power supply and it should do something. If it does, replace the RAM and hdd it should now restart. If nothing, check the GPU.

Does it actually have a wireless network adapter? Check the network adapter settings. Does it show both LAN and wireless? If it does you may need to use one of the Function keys to launch the interface to turn on the wireless.

Screeen is upside down


If you have a Windows OS, press and hold the ALT and CTRL (control) keys and then press the Up arrow. (If that doesn't work, try holding the Alt and CTRL keys and pressing the left (or right) arrow key twice.) If that fails, right click on the desktop (Windows+D will minimize all programs), anywhere with no running programs or icons. Then select the Screen Resolution option. Look for the line Orientation; use the drop down menu to select the correct orientation. Click Apply and then confirm the setting change if a confirmation window pops up. (This works in Windows 7 and 8.) For older Windows versions on laptops, you may need to select Graphics Properties (or a similar line) and then repeat this. The Windows screen rotation option is dependent on your video card. With some models, you'll need to open the graphics card properties to undo the rotation. You should see a line for the graphics adapter when you right click on the Display.

For Macintosh OS, make sure that the System Preferences is closed. Then open it by pressing Option/alt + CMD . Select the line Display. Find the button labeled Rotation: Standard then choose the correct screen orientation.

I hope this helps.

Button keeps blinking


It sounds like it could be either the battery is going bad and not holding a charge or the adapter is. I have had really good luck with similar problems going to places like Batteries +, and large electronic retailers, and my favorite the small local mom and pop computer store; where I end up asking them If I could try one of the adapters from the floor model to eliminate if is a faulty adapter. Other then that I'd if its not out of warranty contact Acers online chat support at http://us.acer.com/ac/en/US/content/service

Freezes on the warm boot screen MC9000


This can be for a number of reasons.

First thing would be to try and cold boot the device:-

Remove battery half way, hold power button and trigger, push battery in fully until click and then release power and trigger

If that fails next thing would be to try and re-flash the operating system. This is done by using an SD card and loading the latest operating files onto it. The SD card slot is located under the keypad. A cross head screwdriver is required to remove the keypad. Search on symbol software download site for the latest. The download also has a readme with detailed instructions. Once the files are on perform a cold boot.

Remove battery half way, hold power button and trigger, push battery in fully until click and then release power and trigger. Drop the terminal in a cradle so that it runs on external power.

Hope this helps.
