same here
I do follow youtube video to disassemble it, however I only managed to unscrew 1 out of 3 screw
tomorrow might call Ban Leong to ask how much to repair

aww that was late until I saw this post
I just buy the switch from the garage sales and ask my friend to switch it
now working like new one
if next time having the same issue might give it a try

but I thought deathadder elite = upgrade version of deathadder chroma
so suppose to have the onboard memory as well ?

I do called razer distributor in Malaysia, they said only replacement no repair = ask me buy a new one
