Software repairs. 1. Press F8 immediately after booting to the advanced option and then let go, and select "The latest correct configuration" Enter to repair.

2. If it doesn't work, press F8 to enter the safe mode to restore the system or reinstall the system.

3. After reinstallation, there is still a blue screen, it is recommended to overhaul it, if you can enter the safe mode, it means that you have installed inappropriate things, uninstall all the inappropriate things before the accident, or restore the system or reinstall.

Hardware fixes. 1. If such a problem occurs, it is caused by software conflicts, inappropriate drivers, and system problems, can you restore the system in safe mode, or not reinstall the operating system, do not install software, patches, drivers, etc., and see if there is still a problem with booting? If you don't install drivers, patches, and software step by step, and find something that isn't suitable, don't install it.

2. If there is a hardware cause, take out the motherboard battery and put it on the charge, plug and unplug the memory, clean the graphics card, check whether there is a problem with the hard disk, and if it doesn't work, just overhaul it.

3. Take out the motherboard battery and discharge it, which is caused by disk damage.

Lenovo notebook power indicator keeps flashing but can't turn on the reason and how to deal with it:

1. Excessive use of the laptop or excessive power consumption of the standby battery for a long time will cause the power supply of the laptop to be insufficient, and it is recommended to charge more before use to solve this problem.

2. There is no reflection when the hardware is loose or the laptop is flooded. If the hardware is loose, open the notebook and reinsert the loose hardware; If the hardware is damaged, it is necessary to replace the damaged hardware after testing with a professional instrument.

3. The hardware is loose or the COMS data is wrong, resulting in a prompt that the serial port and parallel port cannot be recognized when the machine is turned on.

Hard disks, etc., need to be troubleshooting by reinserting and unplugging loose hardware and restoring COMS data.

4. The computer alarm cannot enter the system. Whenever the computer starts up, it sounds "Flute." The alarm sound of the "flute" is caused by hardware error or damage. This kind of fault needs to be repaired according to the different alarm sounds.

5. The operating system cannot be started. This type of problem is always reflected in a system boot error or reboot after the hardware detection is completed, and the solution is to restore the system or reinstall the system.

1. Check whether all the plugs of the power supply and the wires on the adapter of the notebook are firmly inserted into their respective sockets, if not, it means that the contact with the power supply is poor, just press the plug down again.

2. If the indicator light is not yet on, on the premise of ruling out the power adapter, it must be that there is a problem with the power chip of the motherboard or a short-circuit breakpoint, and the motherboard is not powered on.

3. If the indicator light responds but the screen is black, it may be a problem with the graphics card or memory.

4. There is no display when the boot is normal, check whether the power cable, switch, and data cable of the display are correct, and it is also possible that the display is damaged.

Hello, it is recommended that you find a repair master to clean up the dust of the computer comprehensively. To reinsert and unplug each version of the card, wipe the gold finger with an eraser and give the CPU film a good silicone grease. Clean the dust off the fan.

Replace the round battery on the motherboard, go to the computer city near your home and buy it, about ten yuan a piece, and replace it on the main version when you come back. Boot into the BIOS, restore the factory settings of the BIOS, and press F10 to save and exit. After the above steps, your computer will be fine, if it still does not solve the problem, it is recommended that you bring your computer.

Go directly to the official maintenance department or the computer city near your home, and ask the master there to help you see if there is a problem with your hardware.

In this way, you can use the built-in system restore function of the Windows system to restore to a restore point when the computer was able to boot normally.

Hello, it may be a system problem, or it may be a problem with the hard disk or memory. It's best to have it checked by a professional repairer.

Before booting up and not entering the operating system, we press the F8 key, select "Last correct configuration" and press Enter. This method can only solve the situation that you can't enter the system due to configuration problems (such as the blue screen caused by replacing new hardware or loading a new driver), because this method is simple to operate, so you should first take this method when you can't enter the system, if you can't solve it, replace it with other methods.

Restart Sometimes the computer system can't be started after booting is just an occasional phenomenon, maybe it is not fully booted up at that time or individual components are not loaded to start the computer, then you only need to restart the computer.

Lenovo notebooks generally can't turn on the following types:

The motherboard is not powered on. Solution: Try to release static electricity (remove the battery and power cord of the computer, make sure the notebook is in a completely unpowered state, press the power switch 6-8 times repeatedly, continue to press and hold for 6-8 seconds each time, connect the power supply and try to turn it on), if it can be turned on normally, the fault will be solved; If it still can't be turned on normally, it is recommended to send it to the local service station for testing hardware.

Faulty display or graphics card. Solution: It is recommended to send the local service station for testing hardware.

The system is compromised. Solution: If you are using a pre-installed genuine Win7 system, it is recommended to restore the backup data in the logo interface by pressing Alt+F10 with one click; If you are not using a pre-installed system, it is recommended to back up your data and reinstall the system.

Failure of other hardware such as hard disks. Solution: It is recommended to send the local service station for testing hardware.

If the laptop cannot be turned on after continuous charging, please debug it according to the following scheme:

1. Release static electricity.

1. If the notebook only has an "external" battery, the operation method is: after the main power is turned off, unplug all the connecting wires and connecting devices on the fuselage, remove the external battery, press and hold the power button for 10 seconds, press and hold it 3 times, replace the battery after the operation is completed, and connect the power adapter.

After booting the computer and trying again.

2. If the laptop uses a "built-in" or "built-in + external" battery, you can find out whether the back of the laptop has a round needle eye.

The size of the hole, the word "reset" is written near the hole, you can unplug all the connecting wires and connected devices of the fuselage in the state of power-off (there is an external battery that needs to be taken out), poke the button in the "reset" hole with a paper clip or a card needle, for 15 seconds, after 15 seconds to check whether the host has been started, if not, you need to connect the power adapter (if there is an external battery, the external battery will be connected first, and then connected to the power adapter), and then boot the test.

2. Replace the same model power adapter for testing.

3. Try to replace the external battery of the same model for testing.

If the machine is fully charged, and the battery cannot be turned on after unplugging the power adapter alone, it may be that the battery is not charged, and the external battery is replaced.

4. If it still can't be turned on after the above operations, or if it is confirmed that the power adapter or battery hardware is faulty after the replacement test, it is recommended that you consider repairing.
