Default What do these capacitors do.. ?

Hello
Please can someone shed some light to what these 3 capacitors actually do.
C5502, C5503 and C5504.
I am waiting for new ones to be delivered plus the fuse.
I am expecting the fuse to arrive first so would like to know if I can try the laptop after ive replaced the fuses without the capacitors.
Or even does the laptop need these capacitors to work ?
See attached

Cheers

Filter caps.
Are they tested bad or what?

yes motherboard had a short to ground, apparently all three capacitors and fuse needed replacing, repairer couldn't return them as he lost them?? , I have ordered new.

What would happen if I turn on without capacitors soldered onto board?

Cheers
