Can consider AW15/17

Set a budget to make things easier

Preferred max weight in kg (light is too vague) and battery life in hours?

Some ppl thought that 3kg is light while some ppl said 2kg is heavy. Everyone have different preference. Give me a range in weight so that I can help you to choose

How about battery life? You haven't answer on that...

For around 4k you can consider Ultrabooks like HP Envy 13 or Lenovo Ideapad 720s 13 (Intel). If battery life not so important you can get Dell Inspiron 7373/7472/7570, Acer Swift 5, Dell Latitude 5290 2 in 1. Many Ultrabooks have soldered RAM and limited storage thigh.

Or gaming laptops like Lenovo Y530 (300 nits panel), Illegear Raven (120Hz), Asus GL503GE

Budget still low for your usage, I'll suggest at least KBL-R i5 CPU and 8GB RAM

For that price you won't find a 17 inch gaming laptop that's better than W15 Lite (Clevo N950TP6)

AW17, Illegear Z7, Asus GL703GM

That one is Clevo N870, OKish build quality and OK-mediocre cooling

Dell G7 or Illegear Raven. Add RAM and SSD manually, usually cheaper

If you're fine with worse build quality and cooling then yes

13 inch laptops usually don't have much power and have limited cooling. Is 14 inch OK to you?

Also your budget is overkill

If you're fine with low sRGB display then Swift 3 (SF314-54G). 8250U is enough, 8550U is usually not worth it

Asus UX430 and UX331 also an option, however they have cooling related issue

I would suggest 8750H (with good cooling) and 16GB RAM, however this is out of your budget (by a bit)

If that's the case then go for 8300H laptops, with 16GB RAM upgrade if you have the money. Dell G7 or Illegear Raven have good cooling. Raven has optional 120Hz panel which is better than the entry level IPS in G7 and the stock panel in Raven. For multi monitor setup you might want a custom laptop (Clevo, TongFang, Quanta etc) since they have tons of output ports

You may want to try out the keyboard first, not everyone's taste

XPS 13 is excellent enough

1. No way for 720s 13 (Malaysia models), also cannot upgrade (soldered)
2. Need to manual upgrade (not all models)

May I know your budget, usage, preferred weight and battery life?

Raven has in house mechanical keyboard (a unique feature in TongFang barebones)

If you don't have much requirement on battery life then can go for performance laptops (eg gaming laptop)

Are you fine with 2.5kg max weight?

Then Illegear Onyx as suggested above
