Hp omen 15 laptop wont turn on

[Omchi20]

Hello,

Yesterday when I turned my laptop an error occurred saying that the fan wasnt working therefore it would automatically shut down if I didnt press enter, however continuing by pressing enter to start the laptop could result to damage.

I noticed the right fan of my laptop was not spinning correctly, it would spin and than stop with a noise. So after searching the internet I decided to clean the fans. So Today after cleaning both fans (and there was a pile of dust), my laptop would not start instead the power button started to blink red, also when I plugged the charger the red light would turn on. After again searching for answers on the internet, Ive found that removing the battery, than pressing the power button for 15 seconds-and re-inserting the battery would solve the issue for example. However it did not, on the contrary the power button wont even blink nor the red lamp when plugging the charger in. Could it be possible that I damaged the motherboard? 

if so is it possible to save everything c + d drive for example if i purchase a new laptop?

it just sucks that after trying to clean the fan according to professional youtube videos (high views and likes) suddenly another way bigger problem occurs…

if someone has experience with same issues or any advice please let me know. I would appreciate it a lot in advance.

in addition the thin red/black cable has snapped off from one end, after searching those for what those cables are for or connected too it seems that they are for the speakers or WiFi? Although It wont affect wether the laptop is booting or not.
