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.
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.
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.
