What do you mean with "open"? Maybe "turn on", or "boot"?
Then it might be you damaged it by cleaning (with too much water or whatever liquid you used). You can try to replace the keyboard, but just as well it's possible the motherboard is damaged and needs to be replaced.
Find a repair shop and let it have a look.
PS. The most prominent Zedair laptop I find is a 32 GB Windows 10 laptop. A Windows laptop with that amount of memory is a rather bad choice. Most owners regret in within a year.
I can't open my laptop since i cleaned my keyboard. The power button won't work and my battery is fixed . When i connected it to the charger a red light (charging) and blue light but it will disappear . Sorry for my english. Thanks i hope you can help me.
