My laptop can't boot without power cord

I recently spilled some coffee in my laptop, which unfortunately have caused some failures regarding the boot up.

When my DC cable isn't plugged in, i am not able to boot the laptop. However, if i plug my cable in, boot it, and unplug the cable there is no problem.

Could it be the CMOS battery, or some circuit on the motherboard which took some water damage during my little coffee-incident?

I haven't experienced any checksum failures, nor clock resets.

At the moment i'm not able to provide you with the name of the computer, but it's a Zepto Znote (Unknown danish brand) and it's about 3 years old and is running Windows 7.

Thanks in advance!

Why not?

Why not try the (cheap) CMOS battery since what's next is the mainboard, cables and more. Those are much more expensive.

To repeat. Try the cheap stuff first.

other reboot options?

Have you tried other shutdown and startup options such as standby or hibernate? I'm not saying that you need to use these from now on, just curious as to wether the problem persists with these different methods or wether its just a problem with full shutdown or restart... Also, have you noticed any decrease in battery life or performance? After you spilled the coffee did you open the laptop and thoroughly clean it with medical wipes or just let it dry?

Thanks for your replies! glad someone can assist me in this area!

I can reboot without the power cord connected though. It's only when the laptop is shutdown i encounter these problems.

I opened the computer after the incident and dried it with a regular hair-dryer. No, i haven't noticed any other symptoms regarding decrease in battery performance.
