Precautions for the use of laptops:

1. Do not use in an unstable environment. This is very harmful to the hard drive, and in severe cases, it will invalidate the hard drive. Note that it is best to turn off the computer for more than 20 seconds before moving the laptop.

2. Do not use it in an environment where the temperature is too high or too low, which will affect the LCD display and battery. The low temperature is not less than 10, and the high temperature is not more than 30.

3. Please stay away from magnetic materials such as microwave ovens and family speakers, which will cause great damage to the hard disk, and even make the data of the hard disk disappear. This memory is far away from electronic devices such as mobile phones that generate high-frequency signals.

4. Maintain your laptop regularly, a laptop is a relatively "delicate" device, so you should pay attention to its regular cleaning and maintenance to prevent crashes and stalls. <>

Reasons and solutions for Lenovo Y480 laptop not turning on:

1. The power supply of the laptop is insufficient. This situation is caused by excessive use of the laptop or excessive power consumption of the battery that has been standby for a long time, and as long as you charge it more before use, this problem will be solved.

2. There is no reflection when the machine is turned on. This type of situation is generally caused by loose hardware or water ingress into the notebook. If the hardware is loose, just open the notebook and reinsert the loose hardware; However, due to hardware damage, the damaged hardware should be replaced after testing with a professional instrument.

3. When the machine is turned on, it prompts that the serial port, parallel port, hard disk, etc. cannot be recognized. This type of situation is usually caused by loose hardware or the same error of COMS data, and can only be troubled by reinserting the 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.

Dear users, hello!

This is caused by your network card having the boot function of the boot rom chip enabled, and the network card has a pxe boot chip. It can be solved like this:

If the network card is integrated on the motherboard, or the boot program on the network is written into the BIOS, you can modify the boot order of the system from the BIOS settings, such as setting the hard disk to boot first, or disabling the network card from booting the system from the BIOS. Specifically:

Press F2 to enter the BIOS when the logo appears on boot, F9 restores the BIOS default settings, boot-boot priority order, and sets HDD as the first item.

Or press F12 to enter the Boot Menu when the logo appears at boot, and select Ata-HDD to boot.

If it still does not solve your problem, it is recommended that you go to your local Lenovo service station to test, and the service station staff will solve the problem for you.

This is because the boot device was not found, such as hard disks and optical drives. network, adjust the system startup items or redo the system.

Your system is not compatible with your computer system, and you'd better switch to your original system, which happened to me before.

Adjust the boot items in the BIOS, put the HDD first, and by the way, see if the status of the hard disk in the BIOS is normal.

**This? It doesn't seem to be uploaded.,But for general problems, you turn on and press f8.,Reply to the last normal boot.。 You need to post a specific question** to take a look.

Doesn't Lenovo come with a one-click recovery function?
