Does Lenovo Y50 laptop have nothing to do with the hard disk without boot screen?

There is no picture when the laptop is turned on

1. First determine whether the screen is powered on. Can it be lit.

2. Unplug the battery and use the direct power supply to turn it on. There is a picture when I look at it.

3. If the fault persists, then open the case to check whether there is any excess metal in the case, or a short circuit caused by the deformation of the motherboard, smell whether there is a burning paste smell in the case, whether there are burned chips on the motherboard, and whether the capacitors around the CPU are damaged.

4.If it can't be turned on, then use the minimum system method, unplug the data cable of the hard disk, floppy drive, and optical drive, and then check whether the computer can be turned on. Then connect the above devices to the computer one by one, when connecting a certain device, the fault will recur, indicating that the fault is caused by this device, and finally focus on checking this device.

5.If the fault persists, the fault may be caused by devices such as memory, graphics card, CPU, and motherboard. Then, use the plug-in method, swap method and other methods to check whether the memory, graphics card, CPU and other devices are normal, and replace the damaged devices if there are damaged devices.

6.If the memory, graphics card, CPU and other devices are normal, then discharge the BIOS, use the isolation method, place the motherboard outside the chassis, connect the memory, graphics card, CPU, etc. for testing, if the computer can display, then install the motherboard into the chassis for testing until the cause of the fault is found.

If the power prompt light is on, it means that the power supply is fine, and if there is an English prompt on the screen, you need to look at the English prompt message.

But as long as it can be turned on and does not crash after booting, it is not a problem with the hard disk.

Personally, I feel that there is a problem with the line of the hard disk, which causes the notebook not to be displayed. Powering up is rotating, but powering up doesn't mean it can be read.

Let's see if the wiring is not connected properly, or if it doesn't work, restore the BOIS to factory settings.

Yes. The requirement is that the original HDD has not been used on other computers or laptops.

Replacing hardware may require reinstalling the system!

Won't turn on If the original hard drive still has an operating system, then it doesn't matter!

You are in PE, maybe your hard disk has a bad sector, is there any abnormal sound when your hard disk is turned on?

Dear Lenovo users, hello!

Your problem is caused by your hard disk mode is GPT, Win8 should be Win7, first you need to modify your BIOS, and secondly, you need to repartition your hard disk and change GPT mode to MBR mode.

The hard drive is no longer recognized.

It's possible that it's broken.

It is recommended to try a different hard drive.

If not, look for after-sales.

Good luck.

This kind of problem, if you are not a professional, it is best to go outside to fix it.

One; There is too much dust in the computer hardware, which affects the heat dissipation of the fan, causing the local temperature of the hardware to rise sharply, which will also affect the running speed of the hardware. For example, if the GPU of the graphics card, if the fan stops due to too much dust, it will not only greatly affect the heat dissipation and cause the computer to become a card, but it will even burn out the GPU over time, of course, the same is true for the CPU.

Two; You need to clean up the disk fragmentation, usually in the start menu, or in the "My Computer" properties, and you should also be able to find it in the control panel, but it takes a long time to clean up. You can also use Tencent PC Manager to clean up computer junk.

Three; Newbies often reinstall the system without repartitioning the hard disk for unknown reasons, resulting in the computer continuing to freeze soon after the new system is installed.

No. 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. This is how to solve hunger:

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.

If the NIC is not integrated, you can unplug the boot chip on the NIC or use the NIC to set up the program, and the bootrom boot function that prohibits the old fast return of the NIC can also be turned off, and then after booting, when "press shift-f10 configure...... appearsImmediately press the "Shift+F10" key combination, enter the menu, set the Boot Order ROM to Disable from line 4, and then press the F4 key to save and exit.

It may be a hardware failure or a system failure, you can try it as follows:

Turn off the machine, unplug the power cord, remove the battery, wait for more than 2 minutes, plug in the battery, and try to power on.

If you need to do it, open the back cover, re-insert the hard disk, memory, and graphics card (if you have a discrete graphics card), and try again.

Go to the BIOS to see if the hard disk can be recognized, if not, the hard disk is broken; If you can, you can't enter the system, then use a PE tool to repair the system.

If you still can't get into the system after repairing, reinstall the system.

It's caused by the hardware, so replace the hardware.

Dear Lenovo users, hello!

This is a self-test crash.

Check whether the external interfaces of the host are abnormal, whether the card reader slot contains SD cards, and remove all peripheral tests;

2.Press the DEL button on power to see if you can enter the BIOS, and if so, resume the BIOS default setting test;

If your problem is not solved, you can complain, put forward your valuable opinions, and then transfer to manual service.

Hello! Personally, I think there are more hardware failures. Suggestion.

1. Release static electricity and update the BIOS to try.

2. Try plugging and unplugging the BIOS battery.

3. If the above will not, it is recommended to go to the after-sales service.
