My laptop mouse touchpad is not working

Posted on Tuesday, September 23, 2014 by Unknown


Laptop touchpadWhen the touchpad stops working, there are a few things you can do to try and fix it or work around the issue.
Tip: Since some of the settings do require you to navigate the mouse cursor for troubleshooting purposes use the Trackpoint, PS/2, or USB mouse a temporary fix. If you cannot get the mouse to work see our navigating Windows with the keyboard page for tips on how to use the keyboard to navigate in Windows.

Other USB device

Some USB and PS/2 devices, especially any USB input device (including a computer mouse), can disable the touchpad. As a troubleshooting step, turn off the computer, disconnect all USB devices, then start the computer again to make sure no other device is disabling the touchpad. If this fixes your problem, but the touchpad is disabled again, the next time you connect the device, check your touchpad software settings for a setting that can prevent this from happening.

Check mouse settings

First, in the Windows Control Panel, access the mouse settings and verify the touchpad is enabled. Also, you can adjust the sensitivity of the touchpad to work best for your fingers. Check these settings to make sure something was not disabled or adjusted to cause the touchpad to not work.

Check Device Manager

Second, open the Device Manager and check through the device list and find the touchpad. Check to see that it is enabled. If disabled, re-enable it and test the touchpad. If it is already enabled, change it to disabled, then re-enable it again. Sometimes toggling this setting can kick-start the touchpad into working again.
If there are any yellow exclamation marks, red X's or "Other devices" in Device Manager, any of these errors can indicate there is a problem with hardware in your computer that may be causing the touchpad problems.
  • Identifying problems in Windows Device Manager.

Check CMOS (BIOS) setup

Make sure the touchpad has not been disabled in the CMOS (BIOS) setup. In the setup, check the hardware device settings and see if the touchpad is enabled or disabled. If disabled, re-enable it, restart the laptop, and test the touchpad.
  • How to enter the BIOS or CMOS setup.

Software driver issues

If the above options do not fix the problem, the software driver for the touchpad may be corrupted or not updated enough to work correctly. Visit the laptop manufacturer's website and download the most current touchpad driver for your specific laptop model. Install the driver, restart the laptop, and test the touchpad to see if it works.

Hardware defect

Lastly, if the touchpad still is not working correctly or at all, you may need to take it to a computer repair shop and have it fixed. It could require replacement of the touchpad itself or another component in the laptop. If you cannot repair the touchpad, connect and use an external mouse as a workaround.

My computer is running slow what steps can I do to fix it?

Posted on by Unknown


Slow computerTip: This page only covers an overall slow computer and not a computer that has a slow boot up or slow Internet.
Below are steps for Microsoft Windows users that can help speed up the computer or determine why the computer is running slow.

Reboot

If your computer has not been rebooted recently, make sure to reboot it before following any of the steps below.

Background programs

One of the most common reasons for a slow computer are programs running in the background. Remove or disable any TSRs and startup programs that automatically start each time the computer boots.
Tip: To see what programs are running in the background and how much memory and CPU they are using, open Task Manager. If you are running Windows 7 or higher, run Resmon to get a better understanding of how your computer is being used.
If you have an antivirus scanner on the computer, spyware protection program, or another security utility, make sure it is not scanning your computer in the background. If a scan is in progress, it can decrease the overall performance of your computer.

Delete temp files

As a computer runs programs, accesses web pages, and is being used in general, temporary files are being stored on the hard drive. Deleting these temp files can help improve computer performance.
First, we suggest using the Windows Disk Cleanup utility to delete temporary files and other files no longer needed on the computer.
Temporary folderUnfortunately, the Disk Cleanup may not delete all of the files in the temp directory. Therefore, we also suggest deleting temporary files manually by opening the Start menu and enter %temp% in the Search field (in Windows XP and prior, click the Run option in the Start menu and enter %temp% in the Run field). Press Enter and a Temp folder should open. You can delete all files found in this folder and if any files are in use they can be skipped.

Free hard drive space

Verify that there is at least 200-500MB of free hard drive space. This available space allows the computer to have room for the swap file to increase in size, as well as room for temporary files.
  • Determining available hard drive space.
  • Regaining computer hard drive space.

Bad, corrupted or fragmented hard drive

  • Run ScanDisk, chkdsk, or something equivalent to verify there is nothing physically wrong with the computer's hard drive.
  • Run Defrag to help ensure that data is arranged in the best possible order.
  • Use other software tools to test the hard drive for any errors by looking at the SMART of the drive.

Scan for malware

Today, spyware and other malware is a big cause of many computer problems, including a slow computer. Even if an antivirus scanner is installed on the computer, we recommend running a malware scan on the computer. Use the free version of Malwarebytes to scan your computer for malware.

Scan for viruses

If your computer is infected with one or more viruses, this can cause your computer to run slow. If your computer does not have an antivirus program installed, you can run Trend Micro's free Housecall online utility to check for viruses on your computer, as well as remove them. It is also recommended that you install an antivirus program for active protection against viruses.

Hardware conflicts

  • Verify that the Device Manager has no conflicts. If any exist, resolve these issues as they could be the cause of your problem.

Update Windows

  • Make sure you have all the latest Windows updates installed on the computer.
  • If you are on the Internet when your computer is slow, make sure all browser plugins are up-to-date.

Update your drivers

Make sure you have got the latest drivers for your computer, especially the latest video drivers. Having out-of-date drivers can cause an assortment of issues, including slow performance.

Reboot computer again

If you have done any of the above steps but your computer is still acting slow try rebooting the computer again at this point.

Memory upgrade

Computer memory aka RAMIf you have had your computer for more than two years, you may need more memory. Today, we suggest computers have a minimum of 1GB of memory (RAM) for 32-bit system and 2GB for a 64-bit system. By having enough memory for programs to run within memory, your computer will not need to swap information stored within memory to the swap file. If your computer hard drive light is constantly active, its a good indication that your computer is swapping information between your memory and hard drive because of the lack of space in memory.
  • Determining how much RAM is installed and available.
  • How much memory or RAM should my computer have?
  • What type of computer memory to use in a memory upgrade?

Hard drive upgrade

One of the biggest bottlenecks of a computer is the hard disk drive. For anyone with a slow computer or just looking for something to upgrade in the computer to improve overall system performance, upgrading from a traditional hard drive to a Solid State Drive (SSD) will significantly improve the overall system performance.

Run registry cleaner

We normally do not recommend registry cleaners. However, if you have followed all of the above steps and your computer is still slow, try running a registry cleaner on the computer.

Computer or processor is overheating

Make sure your computer and processor is not overheating. Excessive heat can cause a significant decrease in computer performance because most processors automatically reduce the speed of the processor to help compensate for the heat related issues.
  • What temperature should my processor be running at?
Dust, dirt, and hair can also constrict proper air flow inside your computer, which can cause a computer to overheat. Make sure your computer case is clean and fans are not obstructed.
  • Steps on cleaning your computer.

Erase computer and start over

If none of the above solutions resolve your issues, another option is to either reinstall Windows or erase everything and then start over.
Erasing everything and starting over can increase performance by getting rid of old software or drivers that may be on the computer and causing the computer to be slow. Installing a fresh copy of Windows, software programs, and the latest drivers help verify there is no software related issues causing your computer to be slow.

Hardware issues

Finally, if your computer continues to be slower than normal after going over each of the above recommendations (including erasing and starting over), it's possible that your computer is experiencing a more serious hardware related issue such as a failing component in the computer. This could be a failing or bad hard drive, CPU, RAM, motherboard, or other component.

Old computer

If your computer is older than five years, the age of the computer could be the cause of the slow performance. Computers advance in technology and capabilities and newer, more advanced software programs come out to run properly on the new computers. Older computers are not able to run the new programs as well, which can cause them to slow down. If your computer is older than five years, we suggest purchasing a new computer or accept that, if all the above options do not work to speed up your computer, it will just run slower than a newer computer.
