Question: Lenovo b575e - Touchpad stops working after pressing any key on the keyboard
Hello, dear forum users.
After loading the OS, if you press any key on the keyboard, the touchpad and keyboard simply stop working (the touchpad works before all actions). If you connect the mouse via USB, the cursor comes to life again, but the touchpad with the keyboard is still missing.
In this case, all the keys Fn-F1 and Fn-F2 (sleep and turn off the display, respectively) respond. After waking up, the touchpad works again until the first press on the keyboard. What could it be?
AT safe mode same.
If you press F8 before loading the OS and try to select the boot option with the arrows, everything is fine. The row cursor runs back and forth without problems.
What was done to solve the problem:
1) System Restore (March 2016)
2) Editing the parameters LowerFilter and UpperFilters in the registry
3) Reset bIOS settings to default settings
4) Instructions from the lenovo forum with clamping the button in the small hole near the left ctrl
5) Updating drivers
6) Full virus scan with fresh cureit
7) And finally, reinstalling the OS with formatting the system disk
After reinstalling the OS even before the first launch, when setting up the username, PC name, etc. it was already impossible to enter data, history repeated itself. I had to use the on-screen keyboard.
Already broke my whole head, who will tell you what?
Answer: No thoughts, I can unhook the keyboard cable and connect the usb keyboard.

If it rings in the same way, then the lines from the mult to the connector are normal - not on a break, not short-circuited - with normal insulation, etc., and if not normal, then everything is the other way around, including because of the multitasking problem.
Imagine yourself, in my position, as a professional writer who spends most of his flickering day away on the keyboard to get you solutions to all your problems. What if one of my keyboard keys doesn't work? For some it doesn't matter, but some may be driven crazy by the idea of \u200b\u200btheir keys not working properly. Rekey issue not working is not unusual on Windows. Users have repeatedly complained about changing keys. In this article, we'll take a look at how you can use troubleshooting methods to restore your keyboard.

To start by troubleshooting hardware components and other devices, here are the basic steps:
What if the keyboard doesn't respond at all?
This can be a tricky situation for you to be in when you don't just have to fix the problem of changing the key not working, but the entire keyboard. This does not apply to any of the software you are using and should be addressed with an approach that troubleshoots hardware components.
Here are the steps you can follow:
- Start by making sure the keyboard is properly connected to your computer. While this may be an amateur step for many, there is no doubt that this method fixes the problem in quite a few times. For those using a USB keyboard, try plugging it into a different port.
- Wireless keyboard drivers must ensure that the drivers they have installed are working correctly and that you are using the programs that came with the keyboard. For those using a bluetooth keyboard enabled device, check if you have configured your device correctly.
- Then you can try connecting your keyboard to another computer. If that doesn't fix the problem, it is likely that you have a broken keyboard and could warrant an immediate replacement.

You can often see users complaining that the "Shift" on the keyboard does not work for them. This phenomenon is not so rare. It can be caused by various reasons. Nevertheless, this scenario presents a lot of problems for users. Sometimes it even becomes very problematic.
So what if Shift refused to work? Why is this happening? Are there any reasons for concern? Answering all these questions is not as difficult as it seems. The most important thing is not to panic. After all, the problem under study is far from always critical. Moreover, only in rare cases, when the Shift button fails, you have to act radically.
Faulty keyboard
The first reason is obvious. It occurs quite often, but it manifests itself not only in the fact that the "Shift" on the keyboard does not work. The point is that all equipment can wear out. It is likely that the failure of the specified key to work is a consequence of a malfunction of the connected device. How to be? You can either install a new keyboard and check the functionality of the specified button, or try to fix the old one. As practice shows, the first way to solve the problem is the most effective. What's next?
Blockage
Is the "Shift" button on or "sticky"? More precisely, is it not pressed the first time, or does the computer basically not respond to this key? Then you should clean the keyboard. This phenomenon should not be scary. After all this problem occurs often, especially if a person is used to eating right in front of a computer or laptop.
What's the matter? In the most common blockage. Any keyboard needs to be cleaned from time to time. Otherwise, her buttons begin to refuse to work. Including Shift. Therefore, users quite often advise each other to disassemble and clean this component if any problems with the keyboard appear. Surprisingly similar way very often helps to get rid of the problems that have arisen. But even on this possible reasons the reason why the "Shift" on the keyboard does not work does not end there.
Viruses
But the next scenario is not so frequent, but it gives a lot of trouble to users. We are talking about the impact on the operating system of various viruses and Trojans. That is, do not be surprised if an "infection" has settled in the computer, and the "Shift" button on the keyboard does not work. Or if it performs only certain functions that were not originally intended for it.
How to proceed? It all depends on the nature of the virus. The first step is to save important data to the media, and then scan the operating system antivirus program... After that, it is required to "cure" the computer and re-check it. Previously, all that did not respond to treatment are removed.
Then you can reboot the system. And "Shift", if everything is done correctly, will work. Otherwise, you can try to reinstall the OS with preformatting hard disk... This is a must, because this is the only way to completely get rid of certain viruses. Perhaps this is the most serious situation that can only be encountered.
Pirate
The "Shift" on the keyboard doesn't work? The next scenario is also far from rare. And it usually gets fixed without too many problems. Shift refused to work? It is worth considering what operating system is on the computer. 
If the user has bought and installed a license for himself, then the proposed reason is deleted automatically. But often users put pirated Windows on their computers. It is not necessary to be surprised that at one fine moment there was a problem in which the "Shift" does not work. This is quite normal for pirates.
There are several ways to act. The first is to reinstall the OS. Sometimes it doesn't work the first time. In some cases, it does not give any result at all. The second is changing the operating system to a license. If the problem lies precisely in windows versions, the keyboard will start working at full power.
Settings
But not everything is as bad as it seems. Before you rush to buy new equipment or reinstall the OS, it is recommended to check your computer settings. Which ones? Sometimes in operating system special settings are set. Or, for some unknown reason, they go astray. Because of this, the left "Shift" on the keyboard does not work. And the right one is often too. 
To check this item, you will have to go to the "Ease of Access Center. It is recommended to pay attention to" Filtering Settings "and" Sticky ". Here you can try to turn on / off extra optionsassociated with the "Shift" button. The changes are saved, after which you can check the functionality of the keys.
That's all. Now it is clear why the "Shift" button on the keyboard does not work, and how to deal with this situation. In fact, everything is not so difficult. If you cannot fix the problem yourself, it is recommended to contact service centres for help.
