Dell Optiplex 790 password jumper location

Problem:  Bought a refurb dell optiplex 790 computer and upon boot up, I get the following error:

“The hardware Jumper is removed to override the system password setting.  System password has been erased and password cannot be changed.  Please connect the hardware jumper to perform password changes.…”

Since this computer was a refurb, the manufacturer probably forgot to put the jumper back into the normal position.  Should be pretty easy to fix.  Pretty much first day computer tech type of solution…  Problem is, where the heck is the jumper?!?  The form factor for these computers are so small, it isn’t obvious when you first open the case.


The jumper is located under the hard drive so you will need to remove the CD-ROM and then remove the hard drive.  You will see that in picture, one the jumper is set for the clear password setting because it’s set on one pin, aka “empty.”  I then moved the jumper over both pins aka “Normal,” (picture 2) put everything back together and the error message was gone.  Pretty straight and clear once you find the jumper.

503 service unavailable error: WordPress – wp-admin

Problem: I was trying to update my guitar blog so I could start writing on it again and when I put in my user and password within wp-admin, I got the following error:

“Service Unavailable The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.”

The actual blog and content was coming up fine but could not access the WordPress Dashboard after putting in my password.   Last time I saw this error, it meant that the .maintenance file wasn’t deleted after an update.  But I haven’t done any maintenance for quite a bit and the whole site was down, not just the admin portion.


  1. I looked for a .maintenance file in the root of my directory – none found
  2. I disabled all of my plugins – no change
  3. Checked rights – no issues found
  4. I backed up my blog and upgraded to the newest version of WordPress manually – no luck

Solution: I was running out of ideas so I decided to use the reset password option within wp-admin. Changed my password and what do you know, I was able to login to my blog. I have no idea what the issue is but when in doubt, reboot or change the password. This time it was password!


Disk is Locked error when trying to upgrade to macOS Sierra

Problem:  Trying to upgrade to  macOS Sierra on my MacBook pro (15-inch, Mid 2012) and I keep getting an error saying that my disk is locked.  So I’m not able to select the hard disk to install the OS.  Tried rebooting it just brought be me back to the macOS Utilities menu.  Tried reinstalling the macOS option one more time and still got the disk is locked error.

What I tried:

  Went into disk utility and ran first aid pos the HD.  – no errors  and no luck

  Disk Utility again and tried to erase the disk and I got an error saying that the disk could not be unmounted.  i’m sure that is related to the inability to installing Mac OS Sierra

  I tried to reboot to the old OS and when I tried to choose the startup disk I go the error: “Startup Disk could not gather enough information on the selected disk”


Shutdown my computer, powered it back on holding the Command-R combination and was brought to the older mac OS utilities menu.  Went into disk utility and tried to verify disk and got the following error:  “This disk needs to be repaired. Click Repair Disk”    I clicked on Repair Disk  and after a few minutes I got another error:  “Disk Utility can’t repair this disk.  Back up as many of the files as possible, reformat the disk and restore your backed-up files.”

Thankfully I don’t need to backup any files so I chose to erase the disk and reinstall.   After erasing the hard drive I had to go into internet recovery and had to install OS X Lion first and then upgrade to mac OS Sierra.


Amazon Video Crashes on Samsung Smart TV

Problem:   So I finally got Amazon Video  to work after I got the geographic restrictions error taken care but shortly after, Amazon Video will no longer load on my Samsung Smart TV.   I open it and it will sit there looking like it’s loading but will eventually time out and crash.   


  1. Powered off the device and back on again without any luck
  2. I tried de-registering the device on through Amazon’s Video Settings within my account.  No luck
  3. Checked to make sure my content filter wasn’t blocking the app like in a previous post.


I reset the Smart Hub by doing the following:

  • Make sure you are out of Smart Hub and then Press the Menu key on the remote control.
  • Select Smart Hub > Reset Smart Hub
  • You will be asked to enter the PIN (default – 0000)
  • Wait until the reset is complete
  • Open Smart Hub and following the setup instructions

Once Smart Hub was reconfigured, I downloaded the Amazon Video app and re-registered it.  Worked perfectly after.

Note:  Looks like this happened after an update.  Coincidence?  I’m thinking not.  Updates are usually the main culprit when things go wrong. 


Windows 7 Post Installation Must Do’s

I know Windows 10 has been out for quite some time now but my end users still prefer Windows 7.  So with that said, I’m still needing to create images for future use.    So when I have a fresh install, there are two issues I must address before I can move forward with the image:  1.  The local administrator account needs to be reinstated and 2. Windows Update will not function and gets stuck on “checking for updates.”

Issue:  #1.  After the install the local administrator is disabled.  I know that Microsoft disabled it by default for security reasons but I’m a creature of habit and would like to keep Administrator around.

Solution to  #1:  Open a command prompt as administrator and type the following command:  “net user administrator active:yes”  and press enter.  This will now bring back the administrator user and then you can re-enable it through users and give it a password

Issue # 2:   Windows Update gets stuck on “checking for updates” until it times out or I get tired of waiting and reboot, thinking that will fix it.   I don’t know what has changed but Windows Update will not work anymore until I do the following solution:

Solution to #2:  

  • Install IE 11 first thing – Internet Explorere 11 download
  • After that you need to install the following hot fix:  (KB3020369)

Are there any “must tweaks” or fixes that you like to do after a reinstall for your image.  Please leave a comment and share your ideas.
