Bypass/Ignore battery and fan alert on bios/boot (HP Mini 110-3500)

I use HP Mini 110-3500 as a media server for my home network. The battery and fan no longer work but I'开发者_如何学Pythonve managed to figure out some workaraound (removing the keyboard, attaching fan via usb etc.).

The problem is on boot, there are two messages (alert) that I had to press "Enter" in order to continue booting, or the machine will just turn off. So I have to be next to the machine whenever I need a reboot.

I've checked the bios setting but found no option to turn of the warning (or maybe I missed it) Is there any way to bypass these alerts?
