The Lenovo Tianyi 100 notebook automatically shuts down

It is possible that the CPU fan is not working, causing the temperature to be too high, the computer will automatically shut down for self-protection, and there is also a possibility that you are poisoned. Although you have restored the system, it is only the C drive that is good, and the rest is not necessarily gone.

Is that automatic shutdown suddenly turned off with a black screen?

It may be that there is too much fan dust accumulation in the computer, and it should be enough to clean up the fan dust.

Agreed, it should be caused by the CPU fan heating issue. However, it is not excluded that it is a problem with the power supply of the motherboard.

The boot button of this laptop is designed to be more discreet, at the upper right side of the fuselage, near the hinge, it is a long strip with a boot symbol next to it.

Below the screen, in the row above the keyboard, there's a power.

Hello friends,1. Separate notebook screen display; 2。Notebook screen display + external that is, two simultaneous displays, 3.

A separate external output shows the conviction of the dress. The situation you are talking about is that the external output alone is displayed, and you need to switch or set it to mode 2. Laptop screen display + external.

Then operate from the following two aspects:One:FN+F3,Don't press the imitation too fast,As long as you connect to the projector,You can use FN+F3Cycle switching,Until you switch to the display mode you need,If you install a shortcut key driver,There are also menu prompts when switching。

Dear users, hello:

If you can't turn on the machine, it is generally a few phenomena to take the ear.

First, press the power button and there is no response - check the external power supply first, no problem and then see if the motherboard is powered on, there will be LED lights on the motherboard.

Target. Second, the motherboard is turned off and does not turn on - it is generally a problem of insufficient power supply and switching circuits. If possible, use the meter to measure.

Third, there is no signal from the fan to the display, and there is no alarm from the host, which is mostly a memory problem, followed by the graphics card, and there are very few problems with the graphics card. If there is a problem with the graphics card, the alarm will be called.

Fourth, the above three are fine, and the display screen has a small dot that keeps beating Not only the system, but the computer does not recognize the system files. It is usually a system damage or a faulty hard disk data cable.

Please compare it based on the above. You'd better be able to describe the problem in more detail. This gives you more specificity in solving the puzzle.

If the power is occasionally turned off and crashes, only press the power on and off button to turn it on, and you have to unplug the power supply if you can't (if you can't turn it on, you have to reinstall it).

1) Isn't that true for your computer? If not, how did you operate before the computer could not be turned off or was slow? What hardware has been installed, what is it, can you please tell me about it? (If there is an occasional shutdown crash, please press the power on and off button to turn off the power on).

If such a problem arises, the driver is not suitable, or the system problem is caused, can you restore the system, or not reinstall the operating system, do not install software, patches, drivers, etc., and see if there is still a problem with the shutdown? If you don't install the driver, patches, and software step by step, don't install it if you find something that isn't suitable.

2) In addition, it is caused by the card, such as CPU and other hardware temperature is too high, or playing games, watching **, or operating large programs, or the computer has been used for a long time, at this time it is very stuck, you have to have some patience to wait for the computer to recover slowly, click on every page on the computer to slowly recover, and wait for the return to normal staring after the shutdown, if it is still not, just press the power on button to shut down (if the computer is on for too long, my experience is, Restart the computer every once in a while, release the cache, and then play better).

3) If the above methods can't be solved, first soft and then hard, reinstall the operating system, do not install software, patches, drivers, etc., and see if there is still a problem with the shutdown? If you don't install drivers, patches, and software step by step, and find something that isn't suitable, don't install it.

Please note: If you restore the system or reinstall it, when installing drivers, patches, software and other things, be sure not to install the things that affect your accident this time, otherwise it will be restored or reinstalled in vain.

4) If it is caused by hardware problems, it is recommended to overhaul it.

Press the power off button and don't let go for 5-10 seconds.

1.There are several reasons why your computer won't shut down:

1) Defects in the automatic shutdown program in the system file. Enter the command: "rundll32 ,exitwindows" in "Start Running" to see if it can shut down normally, if this command can shut down normally, it means that the automatic shutdown program has some kind of defect, if you are using a Windows98 system, check the integrity of the system files and patch the files in the "Start Program Attachments System Tools System Information Tools System File Checker".

If you use a different system (ME 2000 XP), you can also patch files in the corresponding project. If patching the file still doesn't solve the problem, you can only reinstall the system. If you run "rundll32, exitwindows" and cannot shut down normally, it may be that some system programs in the operating system are defective, but the solution is still to patch the system or reinstall the system;

2) Viruses and some defective applications or system tasks may cause shutdown failure. Check for viruses and close all applications before shutting down. Because some applications are loaded at system startup, you can use the command in the Startup menu (in Start Running:

msconfig"), in order to see if there are any files that affect the shutdown (of course, they will not take effect until they are restarted);

3) Peripherals and drivers are not compatible well and cannot respond to rapid shutdown. You can enter the command "msconfig" in Start Running, select "Advanced" in the "General" tab, and "Disable Rapid Shutdown" in the window that opens.

If you suspect that the peripherals are faulty, you can also uninstall the peripherals one by one to check them so that you can find the affected peripherals.

2.If the computer is stuck and cannot be shut down, you can press and hold the power button to force it to shut down.

1.First, check whether the VGA** cable is firmly inserted into the host interface and monitor interface, then check whether the contact between the graphics card and the motherboard I-O slot is good, and finally check whether the CPU fan is running normally;

2.If the computer starts normally, the original monitor may be damaged;

3.You can remove all components of the computer except the CPU, graphics card, and memory module and boot the computer. If there is a fault in the memory, there should be an alarm sound. If there is no alarm sound, then turn on the CPU and re-detect. If the computer screen is still black, it is recommended to replace the motherboard;

4.If the system installs software and updates patches that cause a black screen, you can try to uninstall the update file;

5.After installing the software on the computer, restarting the update causes a black screen and waits for the update to be completed.

6.Enter the safe mode to repair the computer, if it can't enter the safe mode, please reinstall the system.

The method of getting stuck and freezing when using the computer is as follows:

1. The CPU is overloaded, or it is not working properly. Check CPU and graphics card cooling, dust removal, oiling, or replace fans.

Second, the power supply voltage is unstable and the power supply is insufficient. Replace high-quality, high-power power supplies.

3. Clean and defragment disks frequently.

1. In the "My Computer" window, right-click the drive letter you want to clean up - "Properties" - "Clean Disk" - check the files you want to delete - OK - Yes.

2. Clear the temporary file, start-run-enter "%temp%"-OK.

3. Clean up the registry and junk files with Optimizer or Super Bunny.

4. Close some startup programs, start-run-msconfig---start, in addition to anti-virus software, input methods can be turned off in general.

5. Delete unused program software.

7. Reduce the burden of memory, and do not open too many programs. If you have too many documents open or too many programs running at the same time, you will not have enough memory to run other programs, so you should close the programs and windows you don't use at any time.

4. Upgrade the graphics card and network card driver, and change to a higher-grade graphics card.

Fifth, increase the physical memory, now the memory is generally at least 2G.

6. Set up virtual memory reasonably.

1. To play games, the virtual memory can be set to be larger, and the maximum and minimum values are set to 2-3 times of the physical memory.

2. The method of setting the virtual memory is: right-click on my computer - Properties - Advanced - Performance Settings - Advanced - Virtual memory change - Select the partition where the virtual memory (page file) is stored in the drive list - Custom size - Set the value in the "Initial Size" and "Maximum", then click the "Settings" button, and finally click the "OK" button to exit.

3. The partition where the virtual memory (page file) is stored must have enough space, the hard disk resources are insufficient, resulting in insufficient virtual memory, in a computer, it is enough to set up virtual memory in a partition, and it is not necessary to set it in multiple partitions.

7. Optimize your computer with Optimizer, 360 or Super Bunny, etc.

Changing the operating system is a one-size-fits-all approach.
