Reply: During the installation of the operating system, the product serial number is written in an irreversible encryption method, so the product serial number cannot be obtained from the operating system. If your product serial number is lost, you must ask the purchaser for the product secret Key number.

Hi~

I also have this issue(blue screen of death)

But My OS is Windows 10 LTSC.

Do you have this file(USBport.sys) can use on my OS??  View>>>
Reply: If your system was normal before, the blue screen problem caused by USB may be due to software conflict.

Uninstall conflicting applications and services:

Applications and services such as VMWare, Virtual Box, Hyper-V virtualization services may conflict with USB port drivers on the operating system. You should try uninstalling such applications, and you should also consider disabling Hyper-V on your computer.


It may also be caused by the aging of the motherboard and insufficient power supply to a USB interface. Adjust it in the power settings:

Open "Power Options" in the control panel, then select the change plan settings for the power plan, and click "Change advanced power settings"

Find USB settings and click on it to expand it. Now expand the USB selective suspend setting and disable it.

Finally, restart the system.

Hello,

I've been working on a Surface Pro 3 battery issue for several days now. I've read many forums and tried so many recommendations, nothing works. My SP3 battery icon show: 1) plugged in 2) battery at 255%, 3) if the power cord is removed the device crashes.

I ran across your website during my latest research. I was able to follow all of your steps to download the CMBATT.SYS file and copy to each of the folders you directed on your webpage.

I rebooted my SP3, and now I see no battery / power icon. The device manager is showing your CMBATT.sys file, but it is telling me:

Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)

Great, yes MS is correct. How to override this MS error and allow your CMBATT.sys files to be properly recognized after my installation?

Thanks  View>>>
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.
