Tip & How-To about Computers & Internet

My _ quit working on my laptop/computer. (fill in the blank)

After 28 years of troubleshooting computer systems, I have a tip for all of you non-technical types... that have an issue and don't know where to start.

  1. Before you call a tech, pull out your hair or take your computer to the dumpster, follow these simple steps.

  2. Turn off the computer.

  3. Unplug the computer. (If you have a laptop then you MUST also remove the battery.)

  4. Power all devices off. This means everything. Every Printer, Monitor, USB Device, Mouse, Keyboard, Phone line, Modem, Router... everything that has batteries, a power cord or plugs into the computer. (ONLY after turning the computer off and unplugging it.)

    Helpful Hint: If everything is plugged into a surge protector, turning OFF the surge protector is the SAME as unplugging. This saves time and effort also. You MUST unplug the computer itself though, without fail.

    Helpful Hint: If you are concerned you will NOT remember where to plug something back in, get a pen and some masking tape or a sticky pad and label them... (ie: place a 1 on the tape and put it next to the hole and then put a 1 on the cable that goes in that hole) DON'T WORRY! Most devices that can plug into more than one place won't mind if you move them. Most are color coded already to make it easy to find where they go. (blue plug goes in blue hole, etc.)

    Double Check: Once you are sure everything is off, make sure that any phone lines or cords from modems or routers are unplugged. Anything that can or might supply power to the computer... unplug. If you see a green light on the back of the computer, something is NOT unplugged.

  5. Count to 300 or simply wait 3 minutes for all devices to discharge. Plugging them back in right away defeats the process. (Patience here, allow proper time... make a sandwich, call your Mom, pick your nose, just wait at least 3 minutes.)

  6. Plug in any cables you have unplugged in reverse order. (ie: We turned the computer off FIRST and unplugged it FIRST so we will plug it in LAST)

  7. Turn on the power to all devices (NOT THE COMPUTER ITSELF!) and make sure they are re-connected to the computer.

    Double Check: Make sure all devices are re-connected and have power.

    IMPORTANT!: It is very important that you plug in and turn on ALL devices BEFORE you plug the computer in. Ensure that everything (printer, mouse, monitor, USB devices, Router Cable...etc.) is plugged in and turned on before you place the power cord into the computer.

  8. Plug the computer in. (replace the battery also if it is a laptop, unless the problem IS the battery)

  9. Push the power button and start the computer.


    If I had a nickel for every time that following the above steps resolved a computer problem, I would rival Bill Gates in my wealth.

    Many devices constantly supply power to the computer motherboard and allowing them to discharge can alleviate minor hardware issues.

    If the above steps do NOT resolve the problem. Do not attempt to fix it yourself or from instructions you find on the Internet. Call a technician immediately and tell them everything that you were doing when the problem occurred.

    Computers are the most excellent tool we humans have created and they will work for years without issues IF they are set up and maintained correctly. Remember to have a tech tune-up and clean out your computer at least once every 6 months and Happy Computing!

driver for iphone4 code 28


Important: Device Manager error codes are exclusive to Device Manager. If you see the Code 28 error elsewhere in Windows, chances are it's a system error code which you should not troubleshoot as a Device Manager issue. Cause of the Code 28 Error A Code 28 error is caused by a missing driver for that particular piece of hardware. There are any number of reasons that a driver might not be installed for a device but your troubleshooting of the problem will be the same no matter the root cause.
Error Code 28 Troubleshooting
  1. Restart your computer if you haven't done so already.

    There is always the slim chance that the Code 28 error you're seeing in Device Manager was caused by a fluke with Device Manager or in your BIOS. If that's the case, a reboot might fix the Code 28.

  2. Did you install a device or make a change in Device Manager just before you noticed the Code 28? If so, it's very possible that the change you made caused the Code 28 error.

    Undo the change, restart your PC, and then check again for the Code 28 error.

    Depending on the changes you made, some solutions might include:

  3. Update the drivers for the device. Installing the latest manufacturer supplied drivers for a device with the Code 28 error is the most likely solution to the problem.

    Important: Make sure you install the drivers for the correct operating system. For example, if you're using Windows 7 32-bit, install the drivers designed for that specific version of Windows. Many Code 28 errors are caused by attempting to install the wrong drivers for a device.

  4. Install the latest Windows service pack. Microsoft regularly releases service packs and other patches for their operating systems, one of which may contain a fix for the cause of the Code 28 error.

    Note: I do know that certain service packs for Windows Vista and Windows 2000 have contained specific fixes for some instances of the Code 28 error in Device Manager.

  5. Replace the hardware. As a last resort, you may need to replace the hardware that has the Code 28 error.

    It's also possible that the device is not compatible with this version of Windows. You can check the Windows HCL to be sure.

    Note: If you still think there is still a software/operating system component to this Code 28 error, you could try a repair install of Windows. If that doesn't work, try a clean install of Windows. I don't recommend doing either of those more drastic options before you try replacing the hardware, but you may have to if you're out of other options.
Please let me know if you've fixed a Code 28 error using a method that I don't have above. I'd like to keep this page as updated as possible.

safety precaution in trouble shooting of personal computer


Welcome to FixYa!
As a technical support myself, these are the precautionary measures I follow before I troubleshoot a problem.
  • Make sure you have a back-up disk of all the important files you have on your computer. Make sure you at least update your backup file once a day because you'll never know when your computer will encounter a problem.
If its the computer hardware or a part of it:
  • For extra safety, unplug it first.
  • If there is smell or a smoke, stop immediately what your doing, unplug the computer from the wall and let it cool. Make sure you do not have any hand jewelry to avoid electrocution.
  • Never service a non-serviceable. If there is a label that says something about this, take it seriously. You don't want to make it worse.
If its a software problem like internet connection, or etc...
  • Analyze the problem first.
  • Isolate the cause (is it the website?the internet connection?or the program itself) for this will make your troubleshooting easier and less likely to cause you time because you'll know on what you should be looking for.
Hope this helps for these tips have been working for me all this years. Thank you for using FixYa!
