Mouse heating up all of a sudden

[Salnas]

I've had a g700s for about 19 and play with it sometimes plugged with the battery charging cable and sometimes unplugged (majority of time plugged in due to position that I am on the computer in (slight decline from a recliner arm).

Took the rechargeable battery out about 8 months ago and put in a single standard battery. It had been fine up until today. The mouse started to heat up in my hand. I noticed the battery was rather hot, so I pulled the battery and the mouse started to cool down. This worried me so I figured that a new mouse was in order. We out and got a brand new g700s. Brought it home, hooked it up and was playing with it plugged in as it charged the new rechargeable. This new mouse started to heat up also after about an hour of use with the battery charging.

When I opened it up the battery was once again hot. This was a new mouse with a new battery which leads me to believe that my computers usb port might be at fault for it possibly overcharging or what have you. I'm really not sure what my options are here. Is this possibly a faulty usb port or a problem in the mother board, or is it something else entirely. Any help anyone can give would be highly useful as I'm not sure if I be alright just changing usb ports or if I may have to replace something, or if this is something that I need to drag it into the shop to have looked at.

Are you saying that you used it while it was charging? If so, then the heat should not be a surprise, because most devices are not made to charge, and be used at the same time.

Yes plugged in the new mouse and started using it while charging, but literature with the mouse says that this should be ok. That said an older mouse doing the exact same thing is what caused me to get the new mouse and the new mouse does the exact same thing. Hence the question.

As for heat while charing. I would use my previous 700 while charging it after having it off the cord for a while and never had this battery heating problem. As far as I know hot + battery = bad.

From a techincal level, heat is a byproduct of enegery tansfering into the battery. Now excess could be a bad thing especially if they are or aren't passthrough devices i.e: talking on your cellphone while plugged in. Generally when you overheat the battery like that you are damaging it the hotter it gets and it won't hold a charge for as long. Take the battery out of your going to be playing with it plugged in. However, it could also just be normal for a quick charge. Alot of times it gets super hot because its trying to discharge as its trying to charge.

In that case, try to plug something else into the USB port, and see if it heats the same way, or encounters a different problem that may be caused by a faulty USB port.

Currently have the mouse plugged back into the sister port of the usb to see if it acts the same way. Dont really have another piece of equipement that does a battery charge via usb that I'm willing to plug in at this point and time to be a test. Was planning on checking the different usb's to see if the battery heated up.

Still was hoping for something a little more useful then plug something else in to see if it frys it heh

"hot" is subjective. What is hot? 40C? 50? 70? 100?
Batteries get warm when they are charged. Period. Sometimes it can feel "hot".
A defective USB port would activate the failsafe mechanisms in the charger.

Hi
it may be worth checking the 5 Volt output on your PSU using CPUID HWmonitor or something similar.
Plus you say you put a standard battery into your first mouse did you then plug the cable into it and then it became hot ?

The first mouse I had put a standard battery into it months ago to use for the times I had the charger cable/power cord out of it and had never had a problem until today. Yes putting a standard battery inside of a rechargeable isnt ideal, but it shouldnt have been trying to charge it. Smartest move in the world... ok probably not. Should it have tried to possibly start trying to charge the battery..... umm I wouldnt have thought so after a few months.

Sorry I didnt measure the actual temp. Hot in hot enough that it heated the mouse up in hand enough to to be noticeable and say "what's going on here" and not to be burning hot to the touch but hot enough to once again say "what's going on here". Sorry whats going on here overwhelmed the grab a thermometer instinct

So you put in a non-rechargeable battery and then put the mouse in the charger that was connected to the USB port?
I think youre lucky that it only got hot. That is quite dangerous. Never put it in the charger if you have a non-rechargable battery in there!!!

As a side note changed usb ports to one of my front ones. Have plugged in the new mouse while using it and it seems to not be heating up the battery. So possibly the second heat up was just the battery charging as said above, yet dont remember the other one doing that upon first charge up and with my experience earlier still has me uneasy. Debating about plugging it back into one of the usb slots on the back that seemed to heat and see if it starts again. Also I'll redownload hwmonitor since I havent had to use it for a while.

the 700s doesnt actually have a charging bay as such.. the charger is the attachable power cord. I need to hop on the logitech websight but having perused their stuff on the mouse before this seemed to be something that was alright to do as I understood the charger cord came first in its power useage and only went to the battery upon cord disconnect. Charging a battery when it detected it needed charged. I'll have to start digging through the literature again to find it yet I went ahead with a bit of research.

Also only happened after being like that for a while.. could the normal battery have died and it tried to *charge* it... if so then yes it was a very bad move if so. Let me go digging through the logitech sight to see if I can find the stuff i was reading.

If I messed up then totally my fault, the question then becomes still did I mess up my usb ports and do i now need to replace the hardware.

I doubt it damaged the ports. But It might have damaged the mouse.

Hence why i just went and replace it but then this one heated up the recharable battery upon charging.... its fully charged and in another usb port still plugged in and playing with it and it seems to not be heating up. Guess I'm going to plug it back into the other ports and see what happens. If it doesnt heat up then it was just the charging and my other mouse that panicked me into posting here and if thats the case I will apologize for wasting peoples time.
