I have an asus a45v laptop( windows 7 home) which is useless unless the touchpad is disabled and an external mouse used otherwise it goes crazy every time your hand touches the touchpad. There is no way to disable the touchpad via windows>device manager> mouse you can try to disable or delete the driver but then it just reinstalls everytime you restart and doesnt work anyway. There are also no hotkeys that can do this the only way is to disable it in the BIOS which has worked great for 3 years but now suddenly the setting in the BIOS went back to enable and if I disable it again it goes back to enable every restart.

The clock is also messed up and does not keep time settings anymore. Every time I restart its hours off randomly.

So I checked on the web forums about this and it looks like it could be the CMOS battery but after reading allot I came to the conclusion that the cmos battery is only for keeping the bios settings when the main battery is removed or run down and noT plugged in.

I also concluded that if it were the CMOS battery all the setting would be lost including the date but the date seems to be always correct.

Am I wrong about any of this?

Any ideas what is wrong or how to fix?

Any recommendation for expert notebook repair in Chiangmai with good english?

Most likely the CMOS battery. So, yes, get the battery replaced.

Another alternative would be to also disconnect the trackpad (unplug the cable from the motherboard).

My Lenovo Y500 is known for a similar issue; enterprising folks sorted it out that it was shorting out. Applied black electric tape and problem solved.

The touchpad issue you describe can be caused by using a replacement (non-OEM) power charger. Does the issue still arise when booted without being plugged in to AC power?
