Hi, just want to ask for troubleshooting regarding my acer e560 series. My problem is... it alerts for CMOS Battery low a week ago. then, when I turn on my computer now, it wont proceed... there is no signal on the monitor but the CPU is running. I need to turn on and off the system over and over again to start. it takes 30 minutes to 1 hour for me to use the computer.
You mention the CMOS battery was low but you didn't say if you changed it?
I have a feeling that these are not a battery as we all commonly know but a rather high value capacitor, usually between 0.022F and 10F, "yes, thats right Farads", a 0.22uF or even a 10uF would not last two minutes after the machine has been un-powered,
Swapped many a one in older type video machines over the years, usually between 0.022F and 4.7F, these are usually rated at 3.3V dc working.
Of course it could be a 'soldered in' re-chargeable battery in both case you'll need a little expertise to replace them... but certainly not a 'white coat'.
Yes, thank you. Maybe that's the case, that's why everytime I turn my computer on it won't proceed... but sometimes it does... is this really what it does when there is an error like that... I have to turn the computer on/off over and over again until it boots?
The alerts I am now receiving when I luckily boot up is that... CMOS Settings Wrong, CMOS Date/Time Settings Wrong, F1 to enter setup, F2 to load defaults and continue.
When I press F1, it ask me for password.... I dont know what password will I supply becoz I didn't put any Administrator and User Password before, if its wrong... it fails again causing me to turn on/off again and again the computer.
When I select the second option, F2... checking NVRAM appears, sometimes it works, it boots but always it fails... again I have to turn the computer off, and again turn it on...off... on... off... on...
I just want to ask how to reset its CMOS settings? And if I reformat/reload the whole system... is it ok? Will the error be fixed?
No, no don't try and reformat there should be no need to do, try the back up battery first... but to do this you'll need to strip it down or take it in for repair.
Consider this, all kind of effects can be had when it's on the verge of being able to power the cmos and not being able to... hence my comment about losing it's marbles, but suppose you do reformat the computer and the battery 'is' duff (which you have verified).... your gonna still have the same problem and going to be no better off, so better to sort this warning out first of all.
I can't say where this battery is exactly, maybe someone reading this post will be able to say.... but if as I suspect it's a capacitor type memory retention then it's gonna have to be soldered in, as said it could easily be a soldered in battery.
Best thing you can do in the meantime is just drop a E-mail to that link with a general enquiry about getting the battery, you could alway's enquire on the type.
You are not goiung to get anywhere by resetting the cmos... because the battery is duff and it isn't going to be able to remember the settings.
I don't mean to sound rude, but you should probably take it to a local computer repair shop because it can be extremely dangerous to your computer to try to solder the motherboard when you don't know exactly what you are doing.

in which case you would have to go through it's settings.
