My computer is a brand machine of Lenovo, and as soon as I turn it on, there is a TAB DEL and it doe

Does your Lenovo brand phone come with a card reader? If so, it's likely that the card reader (on the PCI slot) is taking up a CPU interrupt, and it would be fine to switch the card reader to a different slot. If there is no card reader, sometimes the motherboard will also cause such a problem, the solution is very simple, unplug all the cables, and press the power on the host a few times to start it.

Of course,In addition to these two possibilities,There is also a system problem,Sometimes the system is broken, it will also cause this result,Repair or restore a system will be good,The general new Lenovo has a one-click recovery function,These possibilities are excluded,Then consider the hardware,At that time,You can only dial 800-810-8888** for help。 I wish you success.

You press the tab key and it will switch to the boot detection interface to see if the hard disk cannot be detected, and the quality of Lenovo's hard disk is not very good.

There's an F1 or F2 down there, and you can just press it.

No, I don't see the hard disk and the optical area are detected, if not, it's a hardware problem

Call ** to Lenovo customer service.

I hit it when there was a problem with my Lenovo computer.

The service attitude was good.

I came the next day, and I got it done quickly, and I didn't ask for money.

Why buy a brand machine? What I bought was the service.

This kind of problem goes directly to Lenovo, like a hardware problem.

We are a Lenovo store, you call 800-810-8888 to reflect it, it's OK.

If the words tab and del and f12 appear on boot, most of them are hardware or BIOS problems, and the steps to solve them are as follows.

1) Shut down first, carefully check whether the keyboard is connected, re-plug it once, plug it firmly, if it still doesn't work, try a new keyboard. Jujube trembling.

2) If it's not a problem with the keyboard, it's a BIOS problem, press the DEL key first to enter the BIOS.

3) Then select the Load Fail-Safe Defaults option, which is to set the motherboard BIOS settings to the "best" default state, if there is a problem after modifying some setting values, you can choose this option to restore the motherboard to the original state when it leaves the factory.

4) If it still doesn't work, remove the button battery from the motherboard, wait for five minutes, install it again, and then try to open the rock mass machine. If the battery is dead, update it with a new one.

5) If the above method still does not work, if it is a desktop, remove some optical drives, hard disks, floppy drives, keyboards, mice and other peripherals, etc., only keep the CPU, memory, graphics card, confirm whether the boot is still so, if it is still so, it can only be the problem of the motherboard, if the problem disappears, add the peripherals one by one, until the problem appears again, you can judge that the problem is on the last added peripherals.
