Summary. Hello from the above information, your computer does not prompt an error message, is it stuck on this screen? If the hard disk cannot be found in the BIOS, it may be that the power cord of the hard disk is loose, or there is a problem with the data cable1, it may be that the battery on the motherboard to save the BIOS settings is dead, so you need to manually set the parameters every time, and then you can turn it on.

2. It may be that the key system files of the host hard disk are damaged or lost, resulting in the inability to enter the system. 3. It may be that the host hard disk is damaged, resulting in the inability to read the hard disk partition and dataHello, it should be your boot sequence wrong, try it: press F2 (in order to enter the BIOS interface), press F9 (restore the BIOS to the factory), F10 save the BIOS settings, and reboot it!

Either the system is broken and the system is reinstalled.

This is a common problem of Lenovo computers, the motherboard button battery is out of power alarm, just replace the buried jujube battery. After the computer is turned on, this painting and makeup have something to do with your improper operation before shutting down, right? For example:

In terms of hardware, such as hard disks, memory, graphics cards, motherboards, etc., if there is a problem, if it is caused by hardware problems, it is recommended to overhaul it.

What happened when the computer boot self-test appeared an alarm, and then this screen appeared?

Hello dear, the computer boot self-test appears alarm, and then this screen appears, what's going on? (1) The first reason: that is, the motherboard cannot detect that the CPU fan is running, and the motherboard has set an alarm, so it will alarm after booting

Turn off the machine, turn on the host, power on, and see if the fan is stuck, or damaged. (2) The second reason: the speed of the fan is very slow, the silicone grease of the CPU is dry, or the CPU and the heatsink are in poor contact, resulting in the CPU temperature is too high, and the motherboard has set the CPU temperature alarm, so there is a boot alarm.

Solution: Shut down, turn on the host, add silicone grease to the CPU, reinstall the radiator, and replace the fan with slow speed. Hope mine can help you; Once again, I wish you good health and a happy mood! 

Boot stuck in self-test can not enter safe mode Hello, boot POST hard disk. This is the boot automatic detection of the hard disk, generally caused by abnormal shutdown, will automatically repair the error in the hard disk If there is a boot self-test, then let it self-test, if it is stuck, it is very likely that the hard disk has bad sectors, it is recommended to use PE boot disk to detect the bad sectors of the hard disk and repair. 1. Prepare a USB flash drive or CD-ROM PE boot disk and insert it into the computer.

2. Turn on the computer and press the start shortcut button 3, select the U disk or CD PE boot disk to start into the PE interface, select Win8PE to enter the PE desktop 4, open the partition tool Diskgenius5, select the hard disk with the right mouse button, click Bad Sector Detection and Repair 5, after the repair is completed, then use the right mouse button to select the hard disk, click to rebuild the master boot record MBR6, and then go back to the PE desktop and click Windows Boot Repair, select C disk to repair.
