Logitech M557 Bluetooth Mouse, Gray, Discontinued

I purchased the Lenovo Thinkpad Yoga 2-in-1 Convertible 11.6-inch IPS Touchscreen Laptop(Tablet), Intel Quad Core Processor, 4GB DDR3L, 128GB SSD, HDMI, Bluetooth, Webcam, AC Wifi, Windows 10 Professional and this mouse to be used together. Both came the same day and set both up at the same time.NO receiver is packaged with this mouse. My Yoga laptop/tablet had a built-in BT card combined with the WiFi radio module. The BT version is 4.0 compliant. This mouse works with that BT compliance.Switched on the BT, ran discover on my laptop. Following the directions set forth by Logitech, I was able to instantly get the mouse paired with my laptop. No "0000" code required.Then a problem. The mouse stopped working. Long story, very short -- Windows 10 has a power save option in Device Manager for BT connections. After a short period of time, the BT portion of the WiFi/BT card goes into power save and shuts down. Others here have complained about this problem thinking it was the mouse that died.Solution: Go to Control Panel > Device Manager > BT Adaptor > Properties > Power Management. You can open advanced properties with your admin password. After opening advanced properties, look for "allow computer to turn off this device" and uncheck the box next to this line. This will not allow the computer to turn off the BT setting by itself, unless you so designate. One more thing, any major Windows 10 upgrade will reset this power saving function back on again. You will have to go back and redo what I described again. One quirk of Win 10 that ignores what the end user's preferences are. I hope this glitch gets corrected in future updates.No additional software is needed to operate this BT mouse. It works with the default Microsoft BT drivers. The Logitech software (downloaded from the Logitech web site) gives you extra functions. For me, it works just fine as is. If you are left handed, then to switch orientation of keys, you will need the Logitech software to switch keys and buttons.After fighting my issues, I really like this mouse. NO dongle to keep track of or break. NO software install, unless you have special need. It just works after I found the solution I listed above.Want a good BT mouse, reasonable price and long life, look no further. Take it home and you will not be sorry. The advice I gave above will save you frustration and a needless return defect for something done by the operating system of the computer.One last point -- this mouse has an invisible laser light for movement sensor. This is unlike the red glowing light from other laser type mice. It is not broken, it is using a laser light beam outside the sight range of humans. Also, DO NOT stare into the light port while the mouse is on. You could have problems with vision being burned.This mouse gets my full 5 star rating and deservedly so.

This is a nice mouse. I never thought I'd say that, because a mouse is a mouse. But this one just works. It connects easily, stays connected, and tracks well on almost any surface. The tracking and scrolling speeds are just right without adjustment, and the buttons and wheel feel just right. No problems with Bluetooth. The box says it works with Linux too, although I didn't test it. You can't go wrong. Just buy it. UPDATE: It works fine with Linux; the mouse is still excellent, but Bluetooth is problematic. Read the update below.The directions are very brief, very easy to follow, and are printed on the inside of the package. To set it up, it takes a couple of minutes to "pair" it to the computer. You just press a button on the mouse and acknowledge it on the computer, and you're done.I got it for a Win 10 laptop/tablet, and the USB-C ports are too close together to hold both the power supply and a wi-fi mouse receiver. I bought a wi-fi mouse, USB-C adapter, and a small hub to make it all work. Turns out, USB-3 interferes with wi-fi, and the mouse action was jerky. With this mouse you don't have to fuss with any of that stuff.==========================UPDATE: It turns out that Bluetooth uses the same frequency band with USB-3 AND 2.4 GHz wi-fi (B and G bands). In my case it worked for several months and then, suddenly it quit working. Bluetooth would instantly disconnect the mouse when I started a wi-fi connection. The computer manufacturer replaced the Bluetooth receiver, with no effect. The problem occurred with that computer running Windows 10 on any 2.4 GHz wireless network, but not with Linux or with any other computer. The only common denominator is the Windows Bluetooth driver for that computer, and I think that's probably the problem.From reviews of other Bluetooth mice, every review I found showed that a minority of people report connection problems--regardless of the price of the mouse. The problem appears to be Bluetooth itself, since it shares frequencies with other wireless standards. The software is supposed to handle the shared frequencies without problem, but it may not be iron-clad.I am now using the mouse with another computer, and it still works flawlessly. I leave it on all the time, but the batteries still last for months and months.
