Re: Acer aspire ONE 753

just check your wiring from your CMOS battery, make sure the red is + and Black is Negative, Wrap your CMOS with electric tape tight enough to connect both wire in your cmos

check your cmos voltage

Re: Acer aspire ONE 753

I,m (little) bit confused now..when the bios battery is connected i get from - pin 3,21+??its like wiseversa..and the battery is original.

Re: Acer aspire ONE 753

OK,must be the wrong battery then..frickin salers,ill switch polarisation

Re: Acer aspire ONE 753

check your male pin slot in your motherboard there is a triangle or a dot there that is positive, like in my first post, maybe a polarity Problem

Re: Acer aspire ONE 753

Cant do any better picture than this one..so theres an arrow on the female connector which means positive and the readings are right 3,21+ and when i set the bios right and take the powercord off and wait approx 1 min they are again in 0..so should i keep the main battery on..newer heard that kind of lappie..

Re: Acer aspire ONE 753

if no adapter connected what is your output in your female connector in CMOS?

yeah its new, but i think its only a CMOS problem,

did you buy same CMOS Type?

its kindda weird

i think the problem is your CMOS battery, try to use other CMOS,
maybe it may Solve your problem, (i guess)

I am a technician also but I did not encounter that after replacing CMOS battery, just replace same model of the original battery,

if you are using cr2032 the normal voltage is 3.0V only
