The computer won t turn off my IBM laptop

Don't know which one you're using? Mine is T43, many years ago. Your problem description is not detailed. It should have something to do with the system, the shutdown program can't run normally, there should be no problem with the hardware, first troubleshoot the software and system, and then look at the hardware.

Forced shutdown. Press and hold the on/off button to reinstall the system after it is turned off.

Power-on no display or can't enter the system when booted? The former is mostly caused by loose parts or moisture damage caused by chip virtual soldering, and professional maintenance personnel are needed to help you overhaul it, while the latter is mostly system problems, and in serious cases, it is the aging and damage of the hard disk, and the notebook hardware is answered.

This book sometimes has to be turned on or something.,Don't use it for a long time.,It's going to break.,I have a machine.,Two months without it.,It's useless.。 It's still been used for too long, and the machine is aging.

Computers, CDs, electrical appliances and other things are not used for a long time, and suddenly there will be problems like this. I don't know what kind of state is under you if you turn it on or not? When you press the power supply, the computer does not respond; It was launched, but the screen went black for a while; Start up for a while and then shut down...

Can't plug in the power supply and use the battery? It is estimated that it is caused by moisture on the motherboard, so find a professional to check it.

"The reason why the computer cannot be shut down normally;

1.In most cases, it is a virus Trojan that causes the computer to fail to shut down normally, and the more typical virus is the kidnapping Trojan, which is a new type of highly destructive Trojan, which is different from the traditional virus, it is by kidnapping the system file registry to achieve boot startup, resulting in the computer shutdown button is missing.

The sound file is corrupted and the computer cannot be shut down.

Incorrect settings will cause the computer to fail to shut down properly.

4.The Advanced Power Management (APM) feature on your computer can also cause shutdown, freeze, or black screen issues.

The computer shutdown does not solve the problem:

One. The computer was damaged by a Trojan virus, and the registry information was maliciously altered. The solution is as follows:

Step 1: Enter the main interface and enter [Kill Trojan].

Step 2 After installation, click on "Kill Trojan" to use the full scan function.

Two. The following describes how to fix the problem caused by a user mistakenly modifying the computer shutdown configuration file.

1.Start "Run", enter "regedit" in the "Run" dialog box, click "OK" to find the following: hkey-local- machine software Microsoft Windows CurrentVersion Policies, click on the "System" folder, and then double-click the "ShutdownWithoutLogon" item on the right.

2., "Start" "Run", enter "Run" in the "Run" dialog box, and then click the "OK" button. In the Group Policy window, double-click Administrative Templates, Taskbar, and Start Menu, and then double-click the Remove and block access Shutdown command on the right.

In the Remove and Block Access to Shutdown Command Properties window, click the Settings tab, select Disabled, and then click the OK button.

Three. The first thing you can do is determine if the "Quit Windows" sound file is corrupted - open the "Control Panel", open "Sound" and cancel the "Quit Windows" sound. If Windows shuts down normally, the problem is caused by quitting the sound file, and you can fix this by restoring the sound file from a backup or by reinstalling the program that provided the sound file, or by defining "quit Windows" as silent.

Four. When you boot up the computer, you can enter the CMOS settings page, focusing on checking whether the CPU external frequency, power management, virus detection, IRQ interrupt opening and closing, disk boot sequence and other options are set correctly. You can refer to your motherboard's manual for specific settings, which has very detailed settings instructions, if you really don't know about its settings, it is recommended that you directly restore the factory default settings.

Five. To check if the Advanced Power Management (APM) feature can also cause the shutdown freeze or black screen issue, open the Device Manager and open the System Devices. In Advanced Power Management, remove the Enable Power Management selection.

If the computer shuts down gracefully, the cause of the problem may be APM. "

It should be good to reinstall or restore the system, and if it doesn't work, go to the repair station and let them check it.

If you have software such as 360 installed on your computer, open the link to see if it is when it is shut down, there are programs that cannot be closed and the shutdown is slow, so you can only reinstall the system.

I think it could be the following:

1.The LCD screen is aging or damaged, take it to the computer city to negotiate with the seller to replace or repair and related costs, and after the warranty period, I have to go to the notebook repair center area to see, so as to bring a friend who understands the cost of notebook repair, so as not to be very slaughtered;

2.The hard disk data and system are directly shut down because your friend is in a dormant state, so the wrong operation of abnormal shutdown leads to the chaos of hard disk data and serious system errors, it is recommended to take the hard disk and go to the hard disk repair center in the computer city to see if they can repair it. It is also necessary to bring friends who understand **, and now profiteers love to slaughter little sheep who don't understand **;

3.Finally, it may be that the screen switching program has been changed, after you turn on the computer, press the fn key in the lower left corner of the notebook keyboard and the f7 in the function key on the keyboard at the same time, see if you can display the screen, if you can make the best, prove that other things are not broken, save money and effort and save time!

Shutting down in hibernation should not harm the hardware. Your friend may not have turned off the power completely, but "hibernated" because the ThinkPad is hibernate by default, not off. It is recommended that you press and hold the power button of the computer until it turns off, then unplug the battery and power adapter, turn on the power after 5 minutes, and turn it back on.

If that doesn't solve the problem, you'll have to go to the Blue Express for a repair!

After turning on the device, press fn and f4 to try, if there is no response, close the lid and open it again. If it doesn't work, just press what you said upstairs, turn on and press F8 in safe mode to see if it can start, it's not a big problem!

Can you hear the sound of the hard disk after turning it on?

It's just that the screen doesn't respond?

Put the mounting disc in.

Power on, press F8 to boot.

If it doesn't work yet.

It may be said that there is a problem with the liquid crystal tube.

If that's the case, it's time to report for repair.
