I have seen the same behavior. In my case it is caused by
activity on a USB3-connected disk. If the disk is attached
but idle there is no interference. But Windows cannot
leave well enough alone apparently, and when I see the
light on the disk flickering I can expect the mouse
operation to get "choppy" for a few seconds.
Spatially separating the USB3 side of the machine from the Bluetooth
side of the machine, may be enough to stop the stuttering.

The nanoreceiver for Bluetooth can be put on a short piece of USB
extension cable, to improve the ability to position it so it is closer
to the mouse.

USB3 emissions have a broad peak at 2.5GHz and nulls at 0Hz and 5GHz.
The most impacted computer signals are Wifi and Bluetooth at 2.4GHz.

In the past, there was no sign of an emissions problem with
USB2. Where the data bit rate and edge rate of the signals
is quite different than USB3.

This is the built in Bluetooth on a Lenovo Thinkpad.


How about disabling the built-in one and using a nano receiver ?
That will at least allow placing the antenna on the side where you use the
mouse.

If I have to do that it defeats the whole point in my opinion. I may as well
use a mouse with a USB receiver. Those work well. The whole point was not to
need USB ports and just have the bluetooth mouse itself. Nothing needed for
USB at all.

I keep spare Bluetooth here, just for experiments.

The experiments usually fail.

And that's the beauty of Bluetooth.

if you have to plug something in, then it might as well be a wired
mouse.

try the same bluetooth mouse with other computers and other bluetooth
devices (if you have any) with the lenovo.

Shielding is not mandated, nor even twisted pairs, for low-speed.


in other words, usb 2 cables, which support high speed, *must* be
shielded.


See, nospam is our resident God. He has a magical telescope that bends
around the Earth's curvature and sees through window blinds and drapes
with a time scale to see what the OP was, is, and will be using.

Again, his argument was first absolute with a global declaration and now
he hedges to qualify. His premises of proof were his should-be maxims.

Please explain how the weight of batteries does not increase the
weight of the mouse? Oh, magical batteries of zero weight. Got a
URL where I can buy those?


you're assuming a bluetooth mouse and wired mouse are in every way
identical except for batteries. that is of course, a completely bogus
assumption.


Oh, you're right. I forgot that a wired mouse does NOT add the weight
for a radio (Bluetooth or RF). (rolls eyes)

the reality is that some bluetooth mice weigh less than wired mice.


And the reality is that most Bluetooth mice -- OF SAME SIZE - weigh far
more than wired mice.

a typical wired mouse is ~100 grams.

here's a wireless mouse that weighs just 32 grams, which weighs less
than most wired mice.
http://usb.brando.com/tiny-2-4ghz-wireless-mouse_p00511c037d15.html

Claims to last 21 days but limits that claim to only 3 hours of use per
day. Someone using that mouse all day long at work will have to
recharge it in about 6 days. Guess that's not bad if you like having to
keep plugging in your wireless mouse to keep recharging it, a nuisance
not incurred with wired mice. Oh, and no on/off switch, either, on this
itty-bitty device. A search on "pequeno ems071 mouse manual" didn't
turn up any online manual to see if the batter(y|ies) are replaceable;
i.e., if the wireless mouse is serviceable and to know if the product
weight spec includes an internal non-changeable battery or the weight
spec did not include the weight of replaceable batteries.

this one doesn't list its weight, but it can't be very much:
https://www.newegg.com/Product/Product.aspx?Item=0TP-000J-00AV9

https://www.amazon.com/Ckeyin-Blueto.../dp/B00KMLP1BK
3.2 ounces (90 grams), or 2.8 times heavier.

So nospam compares a miniature Blueooth mouse ("the world's smallest")
against another another miniature-sized Bluetooth mouse. Uh huh.
nospam omits the added weight of the batteries without which these
wireless mice are useless. If these mice are serviceable, is the weight
in their specs for the mice with or without batteries?

He won't compare Bluetooth mice to wired mice that are equal in size to
compare weight differences between them. He wants you to miss that he
is comparing apples to oranges. Yeah, and he bitches that I make
strawman arguments. Of course, everyone with normal-sized hands wants
to use such tiny mouse on a regular day-by-day basis for many hours of
continual use. In comparing wired to Bluetooth mice of *similar* size:

Logitech M557 Bluetooth mouse
https://www.logitech.com/en-us/produ...se-m557?crid=7
107 grams
100 mm x 58 mm x 34 mm
The weight is *ONLY for the mouse. Now add weight for 2 AA batteries
(23 grams for alkaline, 15 grams for lithium, or 31 grams for NiMH) for
a total weight of 122 to 138 grams, or 130 grams on average.

Logitech M100 wired USB mouse
https://www.logitech.com/en-us/product/mouse-m100
90 grams
113 mm x 62 mm x 38 mm (which is a tad *larger* than the M557)
Larger but less weight because no radio for Bluetooth *plus* its weight
spec includes the CABLE so the mouse itself is even less weight (no one
lifts the entire cable to lift and move the mouse). A 0.5 meter thin
USB cable weighs about 20 grams, so take that off from the mouse's
weight spec and add, say, 5 grams for the portion of the cable you lift
with the mouse. Aw, hell, say the lifted portion of the cable weighs 10
grams. You are lifting on moving the mouse about 80 grams.

80 grams / 130 grams = 62%. The wired mouse is a LOT lighter, or
conversely the Bluetooth mouse is a LOT heavier.

There are mice with thick cables but then they also don't come with 0.5
meter cables but usually with 2 meter cables, so now you have 4 times
the weight of the cable to remove from the mouse's product weight.
Let's say it's just twice as heavy (because there is no connector on one
end), so the 90 gram product weight comes down 40 grams to a mouse-only
weight of 50 grams.

Rather than conjecture the mouse-only weight of the M100 mouse, I
measured mine - without the cable (just the portion of the cable that
got suspended in raising it to rest atop the scale). 2.1 ounces or 59
grams. Geesh, my conjecture was pretty damn close. My 59-gram M100
wired USB mouse is 2.2 times lighter than a similar-sized 130-gram M557
Bluetooth USB mouse WITH batteries that are required to make it usable.

To be complete, the USB transceiver dongle accounts for part of the
product weight spec for the Bluetooth mouse. That adds 0.32 ounces or 9
grams to the product weight, so the 130-gram Bluetooth mouse comes down
to 121 grams for just the mouse. That is still TWICE the weight of the
same-size wired mouse!

Stacked USB ports have more induced RFI than do side-by-side USB ports.
A shielded USB extender cable in one USB port that is near another would
reduce RFI between them. Stacked USB ports are common in desktops but
mobile devices many don't have enough height so they are side-by-side
(sometimes right next to each other, sometimes on opposite sides of the
device). The OP said he has the Bluetooth operational interference on a
Lenovo Thinkpad but gives no model within the Thinkpad product family

the USB 3 and 2 ports are side-by-side; however, another pic of
Thinkpads show some have stacked ports:

My problem as well. Two of my devices (laptop and tablet/keyboard) have
only one USB port. The Bluetooth mouse saves me having to use a dongle
or unplugging the mouse receiver when I need the port. Further the mouse
I use has a 2 device capability so I just push a button on the mouse to
change devices.

My Bluetooth mouse does the same thing on both the devices (Lenovo
laptop and Acer tablet/keyboard) I use it with. It feels like the mouse
goes to sleep while being neglected and then when next used takes a
second to wake up. I figured it was for battery longevity? The
occasional slight delay never bothered me that much so I've never tried
pin it down.

flats happen, but they're very rare. you're actually confirming my
point.

it's also why automakers switched to the space-saver spares. there's no
need to carry the weight and bulk of a full size tire when it's rarely,
if ever, needed.

when is the last time you had a flat?

no they don't weigh 'far more'.

it's very clear you've never used a wireless mouse of any sort, nor do
you understand the specs *you* quoted.

the two logitech mice in the example *you* gave below have a difference
of 17 grams.

a usa quarter weighs 5.67 grams. three of them is 17.01 grams.

https://www.usmint.gov/learn/coin-an...-specification
s

a 17 gram difference is hardly 'far more'. it's close enough that
unless you compared the two side by side, you likely wouldn't even
notice a difference.

a typical wired mouse is ~100 grams.

here's a wireless mouse that weighs just 32 grams, which weighs less
than most wired mice.

i said not necessarily.

some are and some aren't.

the one above is *not* heavier.

you were wrong.

yes, it's tiny, and with that brings compromises, but you were only
focused on weight, not run time or anything else. no goalpost moving
allowed.


this one doesn't list its weight, but it can't be very much:
https://www.newegg.com/Product/Product.aspx?Item=0TP-000J-00AV9


https://www.amazon.com/Ckeyin-Blueto...phones/dp/B00K
MLP1BK
3.2 ounces (90 grams), or 2.8 times heavier.


90 grams matches that of the logitech *wired* mouse below that *you*
cited.

so, not heavier than a wired mouse. it's the *same*.

you were wrong again.


Logitech M557 Bluetooth mouse
https://www.logitech.com/en-us/produ...se-m557?crid=7
107 grams



Logitech M100 wired USB mouse
https://www.logitech.com/en-us/product/mouse-m100
90 grams


as mentioned above, a whopping 17 gram difference.

here's a bluetooth mouse that's 66 grams w/o batteries:
https://www.razer.com/gaming-mice/razer-atheris

aa lithium batteries weigh 15g each:
http://data.energizer.com/pdfs/l91.pdf

the mouse + two aa batteries is 96 grams, or just 6 grams heavier than
the logitech wired mouse you cited.

6 grams isn't anything anyone will notice unless they put each mouse on
a scale.

it definitely does not weigh 'far more'.

three strikes and you're out.

it also uses bluetooth 4 and can get 350 hours run time, but if battery
life is more important, the mouse below boasts two *years* on a single
aa battery, plus it weighs just 91 grams:
https://www.logitech.com/en-us/product/m330-silent-plus



To be complete, the USB transceiver dongle accounts for part of the
product weight spec for the Bluetooth mouse.


there is no need for a bluetooth dongle since bluetooth is built into
most laptops and many desktops.

however, if the dongle weight is included, then the mouse weighs less
than the specs claim.

Which was your tactic: compare miniature with normal size, and don't

It does once you add the batteries.

Whoosh. I was being complete in calculating the actual weight of ONLY
the Bluetooth mouse. The USB transceiver dongle *is* included with the
Bluetooth mouse whether you use it or not.

however, if the dongle weight is included, then the mouse weighs less
than the specs claim.


Yep, my point you regurgitated. I *deducted* the weight of the dongle
to show the weight of the Bluetooth mouse was less; however, after
adding batteries, the Bluetooth mouse is 121 grams, not 81 grams. You
have some magical way to make Bluetooth mice work without batteries?

I hear ya. The point of me buying a Bluetooth mouse (the Microsoft one
with a smooth scrolling surface) was to empty up a USB port being used
by USB receiver. The USB receivers seem never to be affected by
interference at all and Bluetooth - unless you're using a good mouse -
is constantly affected. Is it possible your mouse is just pure ****e?

what's consistent is your inability to read and understand specs and
that you continue to lie about what i said.

*you* cited this mouse:
https://www.logitech.com/en-us/product/bluetooth-mouse-m557?crid=7
Mouse Weight (including battery): 3.77 oz (107 g)

see where it says 'including battery'? guess what that means. take as
much time as you need.

for reference, the wired mouse *you* also cited:
https://www.logitech.com/en-us/product/mouse-m100
Mouse Weight: 3.17 oz (90 g)

you also snipped the example where i explicitly added the weight of the
batteries:

here's a bluetooth mouse that's 66 grams w/o batteries:
https://www.razer.com/gaming-mice/razer-atheris

aa lithium batteries weigh 15g each:

you said wireless mice are heavier. i said not necessarily.

some are and some aren't.

it is *not* a given that a wireless mouse will always be heavier.

you continued to argue, so i looked for the lightest wireless mouse i
could find.

here's a *wired* gaming mouse that's heavier than all of the mice that
have been mentioned:
https://www.razer.com/gaming-mice/razer-naga-hex-v2
€ Approximate weight: 135 g / 0.30 lbs with cable

it definitely does not weigh 'far more'.

nope.

the weight of the batteries are *included* in the example *you* gave:
https://www.logitech.com/en-us/product/bluetooth-mouse-m557?crid=7
Mouse Weight (including battery): 3.77 oz (107 g)

for the second example, the razer atheris, i explicitly *added* the
weight of the batteries.

many bluetooth mice use an internal lithium ion rechargeable battery,
so there aren't any batteries to add.

there is no need for a bluetooth dongle since bluetooth is built into

again, the mouse *you* cited:

do you see bluetooth adapter included? no. you don't, because it isn't.

no mention of a bluetooth adapter included he

Alas, Bluetooth, USB, wi-fi (low-band) routers (especially those with
USB ports for NAS hosts), cordless phones, microwave ovens, baby
monitors, and several other devices all share the /unlicensed/ 2.4 GHz
frequency (if licensing were required then every user would have to get
one before they could use these devices).


it's normally not a problem.


Oh yes, this is our nospam god. Despite all the evidence to the
contrary, what nospam declares must be how it is.


Ain't it great!? First Bluetooth/Wi-Fi interference was "normally not
a problem", now Bluetooth/USB interference isn't either.

That must be why my multi-hundred MB map Wi-Fi downloads on my phones/
tablets increase in speed by an order of magnitude when I disable
Bluetooth! It's all due to non-existing interference.

[We now return to our scheduled "Bluetooth/Wi-Fi interference" program.]
