How to Fix a Blank Screen on a Gateway Laptop M675
If your Gateway M675 laptop is displaying a blank screen, and continues to do so for an extended period, there's likely either an error that has frozen your computer, or it's off. If the screen is black, you'll need to troubleshoot power issues. If not, the best way to fix this sort of error is to restart your computer. You may be tempted to simply hold the power button down to perform a hard reset, but that is not the best course of action, as hard shutdowns can damage your hard drive. Instead, try a few keyboard shortcuts to see if you can resolve the issue or at least shut the computer down gently.
Hold "Ctrl" and "Shift" on your keyboard and press "Esc" to launch the Task Manager. If the Task Manager launches, your computer is not frozen -- it just hasn't loaded your user environment.
Select the "Processes" tab on the Task Manager and click "Image Name." Check for "Explorer.exe" in the list of processes. If you find it, select it and click "End Process." If it isn't there, move on.
Select the "Applications" tab of the Task Manager and click "New Task." Type "Explorer.exe" to restart Windows Explorer, which reloads your desktop icons and the taskbar. If this process succeeds, continue to use your computer as normal.
Hold "Alt" and press "F4" on your keyboard. This shortcut closes the active window; if there is no active window, it brings up a Shut Down menu. Select "Restart" from the Shut Down menu to turn your computer off and then turn it back on again. If the Shut Down menu does not appear, your computer is frozen; if so, move to the next step.
Press and hold the "Power" button until your computer shuts down, then press the "Power" button again to restart it. This works on a standard configuration; however, you can alter these settings. If nothings happens when you hold the button for a few seconds, move to the next step.
Unplug the power cord from the back of your laptop, if you have it plugged in. Close the lid and turn the laptop upside down on a tabletop. Pull the battery release latch to the right and pry the battery up out of its compartment with your fingernails. Wait about 10 seconds and press the battery back into place until it clicks. Turn the laptop back over, open it and press the "Power" button to start it up.
Listen to your laptop for sounds of fan or hard drive activity; if your laptop makes no sound at all, it's off. If you hear sounds of activity, perform a hard reset to restart your computer.
Press the "Power" button to turn your computer on if it is off. If it does not respond in any way, continue to the next step.
Plug your M675's power cable into a wall outlet and press the "Power" button. This eliminates your battery from the list of possible problems.
Tips & Warnings
If your computer suffers hard disk errors caused by a hard shutdown, you may be able to repair them with the command line utility. Click "Start" and type "CMD" into the search bar. Click "CMD.exe" from the list of results. Type "chkdsk c: \r" and click "Enter." Press "Y" and click "Enter" to schedule the check for the next restart. Restart your computer to scan the disc and repair any issues.
If your computer fails to display anything, even though you can hear sounds of activity, you may have an issue with your LCD screen or display drivers. Have the computer serviced by a professional to diagnose the issue.
