After (dis)assembly - cover too big?

[Jimmy099]

Hi,

I have a pavilion zt3312ea,
last week i noticed that the fan made noises like a plane and i looked for a guide to clean this.

i found the maintenance and service guide from hp and started.

to follow the guide wasnt a problem, and i saw some dust at the display and started to clean it too.

then, i wanted to assemble the notebook, and was shocked: the fan wasnt next to the case, the fan was 2-3 cm next to it!
the complete case seemed to be too big!

anyway, i read the guide and built it. the result: the gaps which were 1 mm before - now they are 5!
i cant put the power cable completely inside because the slot is 1 cm more inside...

i started the notebook - all components working, anything semms to be ok.

my question: does anybody knows what i did wrong?
and does anybody knows how i can repair this`?

thanky you!


sorry for my bad english, i'm german...
