First, I'm sorry I answered your both your messages into one. I'll answer separately next time.
Love your Rule 1) and Rule 2)
But oh…it seems everything that can go wrong for me these days, it does. Thank you Peter and thanks again Bruce. On opening my laptop at 9am today I see yet another MS update in progress and as usual no reason given (except pushing into their W11!) I suspect this update has emptied many of my folders (accidentally or deliberately) that I found out when I tried to open them. In my “Computer Info.” folder I have the entire info. in detail on all my devices including the serial numbers, etc. Now I’ll have to go one by one file in the “All Mailboxes” and “All Outlook Items” and transfer them into their respective folders which I’ll try tonight as today I must leave for a doctor’s appointment soon. But I hope first to answer the following:
I always use the external keyboard (and mouse). Dislike a lot typing on those flat keys.
I have the model of the Lenovo laptop:
“Lenovo IdeaPod L-340” as it’s clear and on front of the laptop, but serial # I have it neatly typed with all other info. in my “Computer info.” folder which content is now missing. Otherwise it’s hard to read it on dark grey metal on black background in tiny/fancy fonts that even with reading glasses AND a magnifying glass I couldn’t read. Also, turning over the large laptop (17” with a wire jungle attached) is so hard.
Meantime I may get lucky and find Lenovo’s S/N in my emails as I found this while looking for something else: “Win10 Version 20H2 (OS Bild)19042.928”. You may or may not need it by now?
The mouse scroll button does not turn into a double headed arrow. I don’t have to press the mouse scroll button, I just roll it up or down. What you describe that happens to pages running down uncontrollably, also happens without me doing anything, or when I’m typing or pointing at something.
(But it turns into a 4 headed arrow when I paste something I copy from the net or someone’s email and it’s impossible to get rid of, but not a problem now).
Thank you for clarifying that what I called Extension is actually a USB hub and I agree it may be a very poorly made one. Perhaps I should buy a good one since I need more ports anyway?
“(apologies if I telling you how to suck eggs).” Hahaha! No apologies needed as I can use ever any tech info. really!
“since it sounds like you have an external mouse and an external keyboard both plugged into this hub - this would be the most logical device to take out of the equation initially.” OUCH!!! ☹
I understand thoroughly how important is the S/N to further help me with this problem, especially to disable the trackpad! (Is it possible?)
I just got an answer from my dr’s office where I left a message, that’s okay to come later at 3:00, therefore I’ll devote this time to get my S/N from my email files and if I can’t find it I’ll call Lenovo and get it, maybe along with more info on my machine. Years back I did ask them abvout this problem but they wanted me to ship the laptop to them and I declined as the way they wanted me to shipl it was crazy!
I remind you that I had this crippling problem since decades ago when I had my first Dell computer (good old desktop haha!) which came with its own mouse and keyboard. And it started doing this, many months after I bought it. And that changing computers and keyboards and mice didn’t help. Except…while in the kitchen I didn’t have it! But oh SO inconvenient!!! That’s why I had my bldg.’s electrician investigate but found nothing. Someone in the internet mentioned to cover it with a special type foil papaer. Have you maybe heard such thing?
Thank you both Bruce and Peter for your valuable help. I appreciate it enormously!
