USB Keyboard Not Working – Troubleshooting

USB Keyboard Not Working

A viewer on my Anet Computers YouTube channel had a question pertaining to their USB keyboard not working. I assume they are using a Universal Serial Bus or a Personal System 2 keyboard. They did NOT stipulate it was an integrated laptop keyboard.

"i have tried switching plugs, num lock key, ctrl+alt+shift+del, uninstalling from device manager and restarting. none has work.?"


They tried some initial troubleshooting from a previous YouTube video I had made. They claimed that they tried different ports. You can try booting your computer into windows safe mode.

After your computer turns on and before Windows tries to boot, you want to press F8 until an advanced boot options menu opens. You can choose any of the safe mode options. See if your USB or PS2 style keyboard works.

If your keyboard works in any of the safe modes but not in normal Windows mode, then it could possibly be a drivers issue. They claimed that they already messed around with drivers and could not get this keyboard to work. You can also try booting off of some kind of live CD.

Many linux distributions have live compact discs that you can test to see if your keyboard works. Another test is to try to enter your computer Basic Input Output System. When your computer first turns on you can access a BIOS via an appropriate key.

Many times the F2 key will get you into your BIOS. What I am showing you is how to troubleshoot why your USB Keyboard Not Working. Perhaps, you have a faulty keyboard.

Another possibility is that malware, spyware, or virus(s) might actually have infected your computer. You can always run Microsoft Windows system tools like sfc and or chkdisk.

sfc /scannow
chkdsk /f /r

You can even attempt to reload your operating system and see if that solves your USB Keyboard Not Working.

Laptop Turns on But Screen is Black – Troubleshooting Steps

Laptop Turns on But Screen is Black

A viewer on my Anet Computers Youtube channel is having a problem where his laptop turns on but screen is blankd or black. This ose one of those most common computer problems that occur. He wants to know if it is indeed a problem with this laptop's video or his computer monitor.

"I have a Dell studio 1558 the LCD display when not connected to an external monitor is totally black but when connected it shows weird lines and squares of colours and flickers like anything. Is it my monitor or the video card? Please help....."

He may have answered his own question. The fact that this laptop exhibits same symptoms with or without an external monitor, may be a clue. He could try connecting this Dell studio 1558 laptop to another external monitor.

However, that would be quite the coincidence of both Liquid Crystal Display and an external monitor failing. Here are some quick tips. Disconnect power cable from both laptop and wall outlet.

Take out the laptop battery. Press the power button for thirty seconds to one minute to clear and potential Electro Static Discharge. Connect power cable to laptop and wall outlet.

Install the battery again. Now try to power on this laptop computer and see if this laptop turns on but screen is black. Obviously, if the laptop's display works then issue is resolved. However, if you are still receiving a blank or black screen, then try to hook up a known good working external computer monitor.

If neither displays work then most likely a video issue. Laptop computers are shipped with Graphics Processing Units that are integrated meaning soldered onto the motherboard. Another tip is try to make certain that this is not an operating system problem.

Make certain whether or not you can see the Basic Input Output System splash screen as soon as you power on this laptop. If you still see a blank screen on both laptop and external monitor then chances are likely that there is a major problem with the integrated video. If you can some how get the BIOS screen to display then perhaps it is a problem with the operating system.

If you are running Microsoft windows then try to boot into advanced boot options menu by pressing the F8 key before windows tries to boot. If your display works when booting into any of the safe mode options but your display does NOT work when booting windows into normal mode, then there is a problem with your Windows installation. This will require further troubleshooting.

Perhaps a driver issue is causing your blank or black screen. These are some quick laptop turns on but screen is black troubleshooting steps.

ESD Electrostatic Discharge – Prevention When Working on PC

Anti Static Wrist Strap Where to Connect

ESD also known as electrostatic discharge can wreak havoc on computer components when servicing a computer. Grounding yourself is what is commonly known amongst computer repair technicians, builders, etc to diffuse ESD electrostatic discharge. One quick way to properly discharge yourself when working with computer components is to just simply touch the computer case on the chassis and or power supply every so often.

You want to make sure that this computer is not plugged into live power. Even if you turn off the computer and turn the power supply switch to off position, this can be dangerous because you are in effect earth ground. You want to make sure that the power cable is not plugged in.

You might also want to press the power button for thirty seconds to one minute to diffuse any ESD electrostatic discharge remaining. Then you just touch either the power supply itself or chassis. If you work on electronics and personal computers quite often, you could purchase an anti-static mat.

They are made out of rubber and will clear ESD electrostatic discharge. These mats come with snap in connections, so that you can connect yourself to them via an anti-static wrist strap. You can also just connect the metal clip on your anti-static wrist strap to these mats.

Another option are to purchase anti-static gloves. They too have a snap in connector to hook to an anti-static mat. Also, you could just connect this anti-static glove to the computer case or power supply just like an anti-static wrist strap.

Holding your components properly can also help. If you have a multimeter you could measure in ohms how much charge you, your computer, and your components have. Then you can measure the difference by using one of the afore mentioned ways to clear ESD electrostatic discharge, and then using your multimeter to measure ohms.

Laptop Keyboard Stopped Working – For Some Keys on Asus

Laptop Keyboard Stopped Working

A viewer of a video on my Anet Computers YouTube channel asked me to troubleshoot why only certain keys on their Asus laptop would not work.

Md. Hasan R*****

"Hi, my some key are don't working,how can I active these are? My laptop ASUS intel core i3 -5010U,2.1 GHz. Inactive keys are N & M & L & , & L & O & word key 9.

please advise how can I active it."

Without knowing an exact Asus laptop model number, I am limited to a certain extent. However, I can give out some quick tips. First thing you could try is to plug in an external keyboard to your laptop.

If you are receiving the same problem then it could be a keyboard configuration setting. You can access "Control Panel" then look for "Region and Language" and make sure everything is set to your country for example United States. Since I do NOT know what operating system they are using I am limited in my troubleshooting ability.

If this does not fix your laptop keyboard stopped working for some keys than you can try removing your laptop keyboard from Microsoft windows device manager. Access "Control Panel" and look for "Device Manager". Once in device manager look for your Asus laptop keyboard under "Keyboards".

You might just see an "HID Keyboard Device". HID stands for Human Interface Device. Right click this keyboard and select "Uninstall device".

You can either reboot your computer so that Microsoft windows detects and loads a driver again or click on a "Scan for hardware changes" icon in device manager. Now test to see if those keys started to work. Another option you can try is to right click your keyboard and select "Update Driver".

Try updating your keyboard driver via either "Search automatically for updated software driver", download, or optical drive via "Browse my computer for driver software". Finally, you can boot your computer into windows safe mode. If all keys work in Windows safe mode, then there your problem is with normal windows mode.

You can always restore your computer back to when all keys on your keyboard worked with Microsoft Windows system restore tool. You may need to reinstall Microsoft windows operating system if all else fails. If some of your keys still do not work, you can try reseating your Asus laptop keyboard connector on the motherboard.

However, this will require you to physically take apart your laptop. There is a possibility that you have faulty keyboard hardware.

Check Disk Command Windows 7 – Can Fix Windows Problems

Windows Command Prompt

Have you noticed your Windows 7 computer acting strange? Is a specific application having problem(s)? Does your Windows 7 computer seem to run slower?

Believe it or not all of those afore mentioned problems can be attributable to hard disk errors. Microsoft has a command called chkdsk that can check your hard disk for errors. This can be a very useful tool for your computer maintenance.

I recommend running this command every few months as part of your computer maintenance. You can run chkdsk on Windows XP, Vista, 7, 8, and 10. You want to open up command prompt with administrator rights first, before you run check disk command windows 7.

On Windows 7 click the Windows start menu button. Type in "cmd" without quotes into a "Search programs and files" field. You will see a command prompt icon.

Right click this icon and select "Run as administrator" from a popup menu. Select "Yes" at a "User Account Control" prompt. A command prompt with administrative privileges is now open.

Now you want to kick off a chkdsk scan. Since your file system is already mounted you will get prompted with this message:

The type of the file system is NTFS.
Cannot lock current drive.

Chkdsk cannot run because the volume is in use by another
process. Would you like to schedule this volume to be
checked the next time the system restarts? (Y/N)

You want type in Y for yes so that the next time you reboot your computer, a chkdsk scan will begin. This allows chkdsk to run on a file system that is not mounted. If you just run chkdsk without any variables it will perform a read only scan and report to you any error(s).


In order to check your hard drive for bad sectors you want to run this command, chkdsk /f /r.
C:\WINDOWS\system32>chkdsk /f /r

Also, you can specify what drive letter you want to have scanned. For example you can actually scan a flash memory drive or a secondary hard drive.

C:\WINDOWS\system32>chkdsk f: /f /r

The /f option will attempt to fix any errors on your hard disk. The /r option will attempt to scan your hard disk for bad sectors. As an added benefit chkdsk will attempt to recover any data on a bad sector and move that data to a good sector.

Also, chkdsk marks that bad sector so that Microsoft Windows does not write any data to that sector again. This is why I highly recommend you run a chkdsk scan periodically as part of your computer maintenance. This scan can take quite awhile depending on factors such as how much data you have, the health of your hard drive, size of your hard disk, etc.

You might want to set aside a couple of hours for this scan to complete. Even on a healthy hard drive a chkdsk scan can take quite awhile to complete especially if you choose to scan for bad sectors. There are five stages in a chkdsk scan when you specify the /r option, to check for bad sectors.

Intel Management Engine – Security Flaw Found in Corporate PCs

Security group Embedi recently found a major security vulnerability in Intel corporate pcs running remote administration software. This flaw affects Intel AMT, SBA, or ISM capable systems. These systems will not be owned by home users but most likely by corporate customers.

Intel manageability firmware version 6.x, 7.x, 8.x 9.x, 10.x, 11.0, 11.5, and 11.6 are affected. A remote attacker can escalate their privileges remotely. This can allow them to access and or install software without your knowledge.

Some Intel servers are not affected by this vulnerability. Intel has created a tool that you can download that will detect whether or not you have a vulnerable system. Intel recommends you try upgrading your firmware on your affected system.

That is if your equipment manufacturer has one available.
