Dear Lenovo users, hello!

According to your situation, it is recommended that you uninstall the current power management driver and power management software, go to the official website** and reinstall it to see if you can choose it, if it is invalid, it is recommended that you turn on the computer and press F8 to enter the safe mode to see if you can choose it.

**On the network: The reason is that the Lenovo notebook energycut driver conflicts with the system's power usage scheme, the solution is to open the control panel to add or remove programs, find energycut, and click on the right to change Delete. Then turn on the power usage plan, and it will be back to normal, or reboot and take a look.

Update your driver on the Lenovo official website.

First, it may be caused by the incompatibility of the updated software with the hardware. It is recommended to press F8 to enter safe mode to uninstall the updated software, and then try to boot the computer.

Second, it may be caused by static electricity, and it is recommended to release the static electricity.

The specific operation of releasing static electricity is as follows:

Bureau Li Shen 1, detachable unplug all the external equipment of the host, including the power cord and battery, press and hold the power button for 30 seconds, and then connect all the external equipment to boot the test There is a reset hole for the non-detachable battery, use a straightened paper clip to insert the reset hole, press for a few seconds and boot the test.

2. After the host is safely powered off, the desktop needs to unplug the power cord and other cables behind the chassis, and then press and hold the power on/off key of the host for 5 seconds, release and repeat.

The reason for the automatic shutdown could be:

1 Check if there is a virus, the computer system is poisoned or caused by malware, if there is a virus, it is recommended to use Tencent PC Manager to disinfect the virus, or if it doesn't work, reinstall or restore the system, you can solve it.

2 Use the hardware test in Tencent PC Manager - Toolbox to test whether the temperature of each hardware of the computer, the CPU fan, and the graphics card fan rotate normally, find out the problem, and change the CPU fan.

3 If the power supply is not enough, then you can only change to a higher power power supply, the power supply has been used for a long time, unstable, then you also have to change the power supply to test.

4 Use your hands to return to the rubber and touch the side of the leak motherboard south bridge, north bridge chip, graphics card chip, if it is very hot, it is likely to be broken and need to be repaired.

The problem of the blue screen Let's consider the virus first, and it is not necessarily feasible to have antivirus software installed. There is a virus that cannot be detected or deleted by the anti-virus software, or it still happens from time to time that it coexists with the anti-virus software. If you don't have anything important, just repartition the hard drive and format it, and completely eliminate the problem of viruses.

And then what, if it doesn't work, the problem is the hardware, and it is said that the memory is incompatible, but it seems that the memory problem is becoming less and less... And then think about the graphics card and the hard drive, and if it's all right, only the motherboard is left, because at least the blue screen won't have anything to do with optical drives or anything like that. By the way, there's also the question of thinking about the power supply if.

It's a system problem. If my guess is correct. The system you installed should be ready in about half an hour.

If you want to be normal, you have to change the system. If you tell people that you want to install it slowly and always press and hold the shutdown button to shut it down, it will flash the motherboard. In Lenovo's after-sales installation, a genuine system is about 120.

1. Clean up the dust inside the laptop, raise the bottom of the laptop or increase the heat dissipation base to maintain a good ventilation environment;

2. Upgrade the anti-virus software of the machine to carry out overall anti-virus and clean up the system garbage;

3. Turn off the startup items that are not commonly used, the method is as follows: press the win+r key combination to call the running window, enter msconfig, click OK, select "startup" to select the card, cancel the loader you don't need to boot, and then OK, you can turn off the boot startup of this program.

4. If the heat dissipation problem of the machine has not been effectively improved after the above operations, it is recommended that you can first try to save important files and reinstall the operating system, if the operating system is still not solved after reinstalling the operating system, it is recommended that you contact the local Lenovo service station and ask the engineer to help you deal with it.

If it automatically shuts down or standby without operation, it may be a problem with the settings. Right-click on the desktop to select Properties Screen Saver Power Supply Select a scenario that suits you from the drop-down list in Power Usage Scenarios, and set Never in the list of Monitor Off, Hard Disk Off, System Standby, and so on below (or set a suitable time).

Open the control panel All Control Panel Items Power Options Select Turn off the monitor (select Never or Set Time) Select Never or select the appropriate time from the drop-down list next to Make the computer go to sleep (Win7 system).

See if it's caused by the above settings (the following is automatic shutdown, the top is automatic standby, if you can't solve it yourself, repair it).

Generally, the automatic shutdown may be caused by the high temperature caused by too much dust in the CPU fan, if so, clean up the dust of the CPU fan and heat sink, and add new heat dissipation silicone grease. If it is not a problem, it may be caused by problems with motherboard parts or power supply, voltage instability, hard disk failure, etc., and the new hardware is not compatible. In addition, a Trojan horse can also cause a shutdown due to a system failure, but the probability of this is very small, restore the system or try to reinstall it.

Lenovo computer power management is gray (please ask me if you have any questions).

This is because you have Lenovo's power management installed, and you can double-click the power management icon in the bottom right corner of the taskbar, and in the power management settings window that pops up, double-click the mode you are using, that is, the mode in which you want to modify the scheme. There are two top selection cards in the pop-up settings dialog box, one is the display, the other is the system, and you can set it up (if you don't understand anything, please consult the customer service engineer).

Other questions can also be compared in the two forums, the idea forum.
