Dear Lenovo users, hello!

It may be that the graphics card driver is not installed properly, and it is recommended that you reinstall it.

If that doesn't work, we recommend that you contact a Lenovo service station.

The following is a link to Lenovo's service outlets across the country and a link to Lenovo's after-sales technical services.

Not as troublesome as the above, let me put it this way, there are only 2 scenarios in your current situation:

There's a problem with your graphics card;

Your graphics card is electrocuted or there is a problem with the interface;

So you can only go to the after-sales service or computer repair place to fix it. And one more thing is ... You can even see your QQ, and you're not afraid of being harassed by others? Delete it now!

Analysis: 1. Display failure.

2. The graphics card is faulty.

3. The connection failure of the data cable is displayed.

It is recommended to try again with a different monitor, it is very likely that it is a hardware failure.

There are two cases: one is the desktop toolbar; The second is the residue after the exit of a certain software, and the solution is as follows:

Materials required: Win7 system demo.

First, right-click on the computer taskbar, and click "Properties" in the pop-up menu.

2. Enter the "Toolbar", uncheck all the checkboxes, and click "Apply".

3. If the black block still exists, it means that it is not a desktop tool, and try to refresh the desktop to see if the black block can be removed.

4. If not, press Ctrl+Shift+ESC to open the task manager, enter the process bar to find the "process", and end the process.

1. Right-click on "My Computer" and click "Properties" at the bottom of the menu bar that pops up.

2. After "Advanced", click the "Settings" button under "Performance".

3. Click "Advanced" above the pop-up "System Properties" window.

4. Next, in the pop-up "Performance Options" window, select "Let Windows choose the best settings for your computer (L)", or check "Adjust to the best appearance (B)", and click OK or Apply to remove the shadows.

5. You can select "Custom (C)", just tick the box below before "Use shadows for icon labels on desktop", and then click OK or Apply.

2. In the computer desktop icon area, find the solution with a small black square on the computer icon, and then click to open, find the repair plan in it, and click to repair.

It seems that there is a high possibility that there is a problem with the graphics card.

Elimination, try using the monitor on another host.

It's okay to install your own console with a different monitor.

You're talking about the small rectangle with a flicker.

You cut the insert into an overlay ,,, press insert on the keyboard

button to switch back.

Analysis: Abnormal display of display colors may be caused by poor contact between memory or graphics card and cables, or poor heat dissipation.

Processing: Generally, it can be recovered by restarting, if it is invalid, the operation is as follows:

1.Shut down (if short press the power switch is invalid, press and hold the switch until the power indicator goes out or directly unplug the power cord) Power off the case, replug the memory module, and wipe the gold finger with an eraser in one direction (the back of the thumb fingernail is also fine), if possible, it can also be installed in different memory slots, and then turn on after installation (before operation, you should also touch the wall with both hands to release your static electricity or wear anti-static gloves). If you can't do it, then it's simpler:

Palm or kick the chassis once or twice (pay attention to the location: the front of the shell on the left and right sides of the chassis that does not have an interface at the back; Attention said: Don't push too hard, of course, don't be weak).

The above may need to be repeated, and if it doesn't work, you need to replace the memory module. If you have more than two memory modules, you need to test them one by one.

2.If the above operations do not work, turn off the power and turn on the chassis, reinsert the graphics card, and plug in the data cable between the monitor and the graphics card. If it still doesn't work, consider that the cable or graphics card is damaged, then replace it with a new one.

3.Enhance the heat dissipation inside the case and the environment in which it is used, and reduce the time spent playing large games in summer.

The method of removing the shadow of the desktop icon on the computer is as follows:

1. Right-click the desktop Arrange icon and remove the tick before "lock a fixed web project on the desktop".

2. Right-click on the settings in My Computer Properties Advanced Performance Check "Use shadows for icon labels on the desktop" in the drop-down list of visual effects, and then press Apply to OK.

Shiliang 3, if the fault is still there, you can try the old way. Right-click on the blank space of the desktop, click the "Properties Desktop Customize Desktop Web" option, and then "Current Home" in the "Web Page" bar, and then "http .".Wait for all the checks in front of each item to be removed ("http ....")In order to add web pages or ** addresses from the Internet, you generally don't need them, you can delete them all), and remove the tick in front of the "Lock Desktop Project" below, and click OK to complete the setting.

4. Another situation is that after installing a certain program (such as the system prompt: whether to add the active desktop item to the desktop), the desktop text becomes opaque. In "Run", enter to open Group Policy, select the user on the left side to search for the management template Active Desktop on the right side, select "Disabled" on the open page, then double-click "Disable Active Desktop" on the open page, select "Enabled" on the open page, and press OK to restart the computer.

No picture, no truth, take a screenshot.

Why didn't anyone say it was a problem with the screen?

This should be a problem with your screen, and it is recommended that you go to the after-sales side of the notebook to deal with it.

The black spot on the LCD screen is damaged and leaking, and this cannot be repaired. Only the screen can be changed.
