"Sticky" mouse and keyboard

[JimCJimC]

The wireless keyboard and mouse of my new all-in-one is erratic, "sticky" - that is, sometimes the mouse cursor won't move, then it shoots across the screen.   Sometimes the keystrokes don't register on the screen, then all at once they appear, sometimes multiple.   

A new keyboard and screen was sent, but no different. With the dongle on any one of the full-size USB ports, the intermittent keyboard / mouse “stickiness” continued.  No extra power use shows on task manager.

For a few days now, I have had a Maxell multi-connector / card reader attached to one of the USB-C ports, and placed to the front of the PC, with the dongle in one of the full size USB ports on the Maxell device. There is thus an uninterrupted line-of-sight between the dongle and the keyboard and mouse. So far, this works ok.

It would therefore seem to be: a fault on the big USB ports;  contention on the big USB ports – I have my WD passport permanently attached for backup on one of them; or the wireless signal between the keyboard / mouse and the dongle at the rear of the main unit can  somehow be interrupted.  As far as I can tell, there is nothing to cause this interruption, and in any case, I would expect the possibility to have been thought of and guarded against in the design.   Certainly there was no such trouble with the previous HP all-in-one, one of the very first.

As the new  arrangement seems to be working, I am not inclined to try to investigate why, but I do reserve the right to revert to HP  should it be necessary.  Even after the warranty expires.

It is also worth noting that having all connections at the back of the unit is not the most convenient, especially the card slot, with a normal desk against a wall, it is necessary to move the whole unit to access them.

You might have gathered from the fact that I had received a replacement keyboard and mouse that I had already been in contact with support,  By telephone.  A very pleasant lady in Roumania, I think she said.  The new equipment was exactly the same, but if you read my report, I managed to work round the problem.  Much as I would like it to be solved properly, I don't see any point in contacting support - the lady contacted me about a week after I received the replacement, and seemed more anxious to close the case rather than resolve the issue.
