I am using a HP Pavilion 13" laptop and I am having this problem.

The screen would blip for a few times and then i cant even connect to the internet. nothing wrong with my other devices in connecting. but after i had some books at the side and under the laptop. the problem seems to be gone. could it be overheating or lack of ventilation?

in fact it is really no comment on it, sometimes it might a panel issue. I always put my laptop on the sofa to do work, but I never facing this issue b4. I think u can send to service center for checking if it is still under warranty (for secure purpose).

thanks for the advice.
