Dear Lenovo users, hello!

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

The computer won't boot, and that's what I generally check.

Now I don't know where the specific problem is, there is no alarm sound, then consider the simplest problem first, such as loose memory sticks, or because of the oxidation of gold fingers, the motherboard cannot recognize the memory, at this time, unplug the memory stick, wipe it clean and insert it.

This usually solves the problem when you start up your computer.

If it doesn't work, if you have a discrete graphics card, you can also unplug it and wipe the gold finger, if the motherboard has an integrated VGA interface, you can use the graphics card interface of the motherboard, and plug in the graphics card after judging the problem.

If the memory graphics card can't solve the problem after wiping, then don't panic, you can take off the coms battery on the motherboard mountain, power it off, and install it after a few minutes.

Sometimes, due to hardware changes, the COMS configuration change may also lead to the failure to turn on, if these are not possible, you need to consider the motherboard or CPU problem.

If there is a problem with the system, you can reinstall the system.

The hard drive is broken, or the initiator data is abnormal.

If Lenovo Z570 newly installed win10 system, the wireless network card can not be opened, it is recommended to deal with it in the following two ways:

2. Qin Chun runs the software, and in its main interface, check the item "Hungry disable wireless network card";

2. Uncheck the "Disable Wireless NIC" item, and the wireless NIC can be started normally.

Method 2: 1. Right-click "Computer" on the desktop and select "Manage" from the pop-up right-click menu;

2. In the "Computer Management" interface that opens, click the "Device Manager" item;

3. On the "Network Adapter" tab, right-click the disabled "Wireless Network Card" and select "Enable".

Hello friends: Liang Yuanzai.

1) After reinstalling the system, is there no network card driver installed, that is, there is no local connection? As a result, you can't access the Internet, and generally in such a situation, you can deal with it according to the following methods:

2) First of all, use the drive disc that was given when you bought the computer, reinstall the network card driver with the CD, and re-computer. If you don't have a CD, you can go to the computer with the network, and use the U disk ** a "extended version (integrated universal network card driver) 190MB" driver wizard, that is to say, there will be a lot of network card drivers on this cavity hail elf, and then insert this U disk into the computer without a local connection, click install, this driver wizard can install the network card driver of this motherboard, restart the computer will have a local connection, and you can access the Internet.
