I bought another display port to hdmi cable and am currently testing it out.

Looks like my Onyx laptop motherboard died and cause the display backlight not to function according to illegear tech support. They need to send this all the way back to manufacturer for repairs and it will take 1-2 months!
Not sure if this is extremely long or normal wait times for laptop repairs...

My battery on the onyx is also swollen after 2 years of usage. Throughout my 2 illegear laptop purchases (Onyx and Z5) I have went through 3 battery replacements. The cost of replacing the Onyx battery is 395 with 50 ringgit discount. Instead, I went to purchase another battery for 150 on Shopee for a similar battery model which is so far ok. So to those future Onyx buyers, bear in mind of this.

Bought from this guy.

Someone reported my post? I wonder why.

Well I had to send my onyx in again as my display ports are dead. Since it’s a mother board issue, I’ll need to wait another 1-2 months. FML.
