Keyboard keeps connecting & disconnecting

Q

Hi,
I have an old Dell workstation T-7500.
I am using " Kensington Pro Fit Wired Comfort Keyboard " which is about one year old plugged into a USB 2.0 port.
Lately it keeps on connecting & disconnecting.
I changed the ports but no relief.
Everything else like mouse & USB sticks work fine.
CMOS battery is one year old.
Boot SSD with Win-7 works fine.
Installed New 6 TB & 10 TB Toshiba Enterprise HDDs about a month ago are working fine.

So what is causing this & solution please.

Thank You.
 
Intermittent connection / poor soldering / joint oxidation ... is a common problem.


Try testing with another keyboard.

If you don't have a spare keyboard, go get one.
It costs ~$10.

You are also the IT guy around here. Wow, so talented.
 
Change to a another USB port and see if the problem goes away. If not, then get a can of electrical contact cleaner and give the USB port a good spray. This cleaner is good for network RJ45 contact.

Could be just the failure of your keyboard. Do you have a spare you can test? If not, you should have one... even a cheap one for backup.

i think I do. Just have to find where I stored it.

Will certainly let you know.

Little scared of fooling around with a 12 yr old rig. I need it badly. Willing to try other suggestions first. But thanks for a lot different suggestions.
 
Scataphagos,

Did buy a 10 TB Toshiba last week & it works with this 12 year old Dell T-7500. In fact it works with 6 TB + 10 TB totaling 16 TB. Just wanted to let everyone know.

Just curious, could that be a culprit ? Will take 10 TB out & see if problem persist.
