Reply: According to experience, I feel that your problem does not have much to do with the CMBATT.sys file. It is very likely that your battery is aging and not working properly.

You try the following methods:

1. In the off state, unplug the battery, then press and hold the power button for 30 seconds to discharge the static electricity, and finally plug the battery to boot.

2. If the system is win10, and the 1903 patch has been updated recently, please restore to the previous state, because this patch may incorrectly determine the battery capacity. You may also wait for the next update, and it will solve the problem.

3. Disassemble the battery, check whether the battery is inflated, or whether the appearance has obvious changes. If there is, the battery is damaged. In this case, replace the battery in time, otherwise there will be an explosion possibility.

4. Check the contact points between the battery and the notebook for rust or poor contact, as the poor contact may affect the notebook's normal use of the battery.

After the battery is used for a long time, the capacity will gradually drop. At the end, the battery will not be used. This is a normal phenomenon. Generally speaking, the battery of the notebook can only be used for 3 to 4 years.

Reply: If you can confirm that the computer's buttons and mouse are not broken, then it is the driver or the system problem.

1. There may be a driver problem. You can go to the official website to download and install the latest driver.

2. There may be a problem with hotkey conflicts. You may think about it, did you install any software recently? If yes, check if the newly installed software has a hotkey that uses 15Key. If so, change it to another button so that it doesn't conflict.

3. It is possible that the computer motherboard is broken. This is very likely, because in my experience, there is no software or virus at present which will cause the mouse not to work. As your current mouse can't work, I think it is due to the problem that one of the lines on the computer motherboard was broken.

Reply: I think that the winload.exe is not damaged, but your hard drive boot information is corrupted. You need to prepare the system disk for repair.

1. Put the system installation disk into the optical drive

2. Set the CD-ROM drive from the BIOS to the first boot, then select Repair (press R to enter the repair), and select the command prompt line to enter the DOS interface.

3. Type "CD C:" in the DOS interface and press Enter to enter C:\; then type "CD Windows" and press Enter to enter C:\windows.

4. Then type "CD system32" and press Enter: C:\windows\system32

5. The next step is to type the following three lines of commands (press Enter each time you type a line, and pay attention to the space):
Bcdedit /set {default} osdevice boot
Bcdedit /set {default} device boot
Bcdedit /set {default} detecthal 1
Press Enter after each command above, then type exit and press Enter; remove the disc, and restart the system.

Reply: This is not necessarily the case. Sometimes replacing the old or new version of the file with the current file will also make the software work. The original intention of creating this website is to solve the problem that the software can not run due to file loss or damage. If your software is running normally, I suggest you not to replace any current files. If your software doesn't work, and you can be sure that there is something wrong with the sihost.exe file, try using a different version of the sihost.exe file and remember to back up the old file before overwriting the file.

Reply: We have the file for Windows 10. According to your system version, download the corresponding bootmgr.efi file, and then restart.

If it can't solve the problem, you can use the Windows 10 installation CD to boot, and then use the "Repair" option during the installation process to fix the bootmgr.efi file. Note: During the installation process, do not select the "New installation" option which will delete the data on your hard disk.
