To clean your laptop's keyboard you have to look under your laptop, you can see like keyboard icons with some scews, so, open them, they will let yout to remove your keyboard.
So now your can remove just your keyboard slowly for some connectors on the motherboard then clean it with a tooth brush.

You can only clean your keyboard with a toothbrush without rmoving it,

Try to remove the space bar key and clean under it.

Try to hard press the space bar for about 5 times, it can release the pusher under the key.

it some liquid was spilt on it you have to remove the keyboard and clean the plastic under ther keyboard.

Hi from what you are describing it looks like the laptop heat sink (fan) needs replacing or the motherboard itself needs replacing

I would recommend that the laptop be booked into a reputable repair firm to investigate further

The BIOS battery could be under the laptop under one of the panels, or it could be under the keyboard. The battery most likely a lithium 3volt battery.

if its not under the laptop, it can only be under the keyboard.

how to check the Ram slot location
1) most laptop have two slots at back, so no other slot under the keyboard
2) some laptop has onboard Ram(on the surface of motherboard) ,if you see one slot at back so no any slot under the keyboard
3) if the laptop no any slot at back it should be one or two slot under the keyboard
your laptop no ram slot under the keyboard
hope it help you to improve your idea
