Acer Aspire 5740G: Cmos battery replacement for Acer aspire 5742G

Wed, 17 May 2023 20:07:21 -0700

I have removed the cmos/rtc battery, but cannot find a replacement for it, as it is a 3v, but very small and with two tangs to re solder it onto the mobo. Amazon say they have it but the battery is only 2v, when looking on their website. Does anyone have an idea where I could purchase one from online?

These are the pics for you, one is obviously for size comparison. The size, according to the digital caliper is: Diameter 12.67 X thickness 2.31 and it is 3 V. It is also rechargeable, from what it written on the back of it and is Mno2 Li, Magnesium Oxide and Lithium, I imagine.If you could provide any other data about it I would be happy. I have tried several online products, AMZ being one of them, but it doesn't show a pic of the battery.

Acer Aspire 5740g: overheating problem, how to open it to clean it?

Sun, 31 Dec 2017 18:15:12 -0700

Hi, I have an Acer Aspire 5740g, last summer it was cool all the way but this summer it's been having some overheating problems.

I'm an IT Technician so I don't do all those stupid mistakes of putting over my legs or whatever, it's overheating even with the back lifted.

So I want to open it and clean the dust because that's probably the problem, but I wanted some help this is my only computer and I really don't want to damage it.

Thanks in advance.
