IBM/Lenovo Thinkpad Ultranav external keyboards (SK-8845/8835/8855)

#1 Post by snap1 » Wed May 20, 2020 2:28 pm

Hi all,

My apologies in advance if this isn't the right forum for such questions.
I'm one of the weird ones who enjoys laptop keyboards with shallow key travel, especially with scissor 'switches' (actually just an enhanced rubber dome with a little cross-arm mechanism to stabilize the keycap) and I always wanted such an external keyboard for my PC.
I don't really want a mechanical keyboard as the switches make too much noise.
Looking around I've found the ThinkPad-like SK-8845 and 8835 for sale on aliexpress and immediately fell in love with them however what's stopping me at the moment is the exorbitant price of these items. I have the money however I'd feel a bit ridiculous shelling out ~100 usd on a rubber-dome keyboard.

I've also considered the new Lenovo USB keyboard with TrackPoint (which is a bit cheaper but way less charming), but I really don't like the chiclet keys.

Could anyone please advise if these units are worth the asking price? What keyboard should I go for?

Thanks and best regards,

Hello, the prices you've mentioned are about the same as being offered in our region.

As keyboards are a very personal thing (key shape as you've mentioned, the "hardness" of keys when pressed, keyboard layout, any TrackPoint or UltraNav on keyboard, if wireless keyboard how solid is the connection, etc.), it's really up to you to decide if the keyboard is suitable for you!

Wishing you fun choosing your external keyboard!

P.S. - There is apparently an older thread about an older model of ThinkPad UltraNav external keyboard (SK-8840) here:

I am in complete agreement with you on Mech vs Thinkpad keyboards. I find them perfect.

Hence I bought 2 TP with UltraNav keyboards when / before I left the US for the first time - not for 100 but maybe 40-60% of the 100 $ price. I wouldnt pay it now, but then my Thinkpad addiction was at peak.

I wish they would take UltraNav and put it with a Bluetooth new system and create one.

I've survived till now but have been giving me some GLITCHES and STICKY keys. It means I'll have to do a full cleanup WITHIN - One of these days before end of the year. Until then I am using a different - Wireless Bluetooth keyboard.

Hello fellow Thinkpadders,

I am a Thinkpads-only person and have been using them exclusively since 1998.

I love this keyboard (SK-8855 AKA 55Y9053). I have 4 of them including 1 unopened that I bought for when one of the others fail. I love this keyboard because of the wrist rest and TrackPoint middle-button scrolling.

I have a new Thinkpad P1 Gen 2 with Win 10 Pro and I have the SK-8855 connected through the thunderbolt dock. The SK-8855 keyboard works and the TrackPoint works for mousing around, but the middle button scrolling only works in some windows and not others:

Middle-button scrolling works when scrolling in:
  • Windows explorer treeview and file view
  • Internet explorer
  • Outlook Message list view
Middle-button scrolling doesnt work when scrolling in:
  • Outlook Message body view pane (the scrolling tooltip appears, but the window doesnt scroll unless I hold the pointer over the vertical scrollbar)
  • Any window at all inside of a VMWare Player virtual machine guest (scrolling tooltip doesnt appear)
  • Excel - trying to scroll up and down causes scrolling left and right when the pointer is over the document, but if I hold the pointer over the vertical scrollbar, then trying to scroll up and down causes scrolling up and down
On prior laptops and prior Windows versions, SK-8855 middle button scrolling was a thing of beauty.

I have tried the latest driver for the SK-8855, which is dated 2011 and doesn't list Win10 as a supported OS.

I have tried the driver for the compact USB keyboard, which is the current model, but it doesnt improve the behavior.

Does anyone have any idea how to get SK-8855 middle button scrolling working in all windows on Win 10?

Thanks in advance.

Mike

Hi snap1,

This keyboard has entered what I call the extortionary lifecycle phase. It used to be the case that when a product was discontinued by the manufacturer, the price was reduced to clear them out to make shelf space and mindshare space for new models. But some opportunists have recognized that if a shopper is searching for an obsolete model, chances are good the shopper has prior experience with that model and prefers it to new replacements, and is probably willing to pay a premium. So they charge 2x - 10x what the product cost when it was current.

That is the case for me with the SK-8855. I like it a lot more than the current model because the current model lacks the wrist rest. I bought extras when i could see it was discontinued. Unfortunately i am having trouble getting the SK-8855 to have full functionality on my new Thinkpad.

Mike
