Yeap, that's the reason I dissembled the laptop, to figure out mine came with WWAN slot just like some of the owner reported. Turned out it's easier to just email them and they will send you full detail of parts and hardware, with photo and parts number.

Honestly I was expecting longer than that due to some of post that I read on their Facebook page. I even read some having inaccurate warranty period.

Means I need to buy another M.2 2242 SSD if I want to use the HDD slot?
So that's not a rubberized finished? What worry me is both my headphone and PC casing rubberized finished ruined by our weather.  So, does it stay just like that or it will get shining and peeled off? How long your Thinkpad already?

Regarding the keyboard, I email them already but unfortunately my spec doesn't come with backlit keyboard, even in the purchase detail spec. I don't mind adding another RM57 for the backlit keyboard but sadly no customization for my unit, just "add to cart". I should've email them regarding that. Sigh... 

As for the warranty, I don't think mine is premium, thus explain the price.

You didn't tick on the RM1 onsite warranty?

Mine ? I think it's been for 1 or 2 months already. Anyway , our laptops are MIL spec graded , so it's not going to wear off easily. Don't believe me look at reddit and see how 6-7 year old thinkpad is still looking good !

You got an option for 3 year warranty ? You didn't pick it ?

Is it this one?  Just realized the on-site repair.

can recommend me 13' laptop for photo & video editing (mainly during travelling) for the brand i prefer dell or lenovo (thinkpad series)

Budget ? Else I'll recommend a RM 20k laptop

and exact photo/video editing ? Professional level ?

Yeah but the Onyx Lite is so nice to look at with thinner bezel and lighter too, but Raven has better specs. Battery life 3-4 hours should be okay, max budget 4k. Having a gaming laptop would be okay too.

Lightroom, Luminar, Aurora for photo

Premier Pro and DaVinci

Max bugdet 6k

Probably gaming laptop would help here , to be honest. You need the GPU power and also the IPS display - it's not for gaming but for rendering

Consider Illgear Onyx if that's the case

Preferred max weight and min battery life? Mind non-upgradable RAM?

been considering Illegear too but the weight 
around macbook 13' weight since mainly purpose for travelling prefer upgrade-able RAM

13 inch+good display+upgradable RAM is very rare, usually they weight slightly more

hmm any recommendation if non upgrade able ram (prefer 16GB if possible)

I do have my own desktop workstation btw

Fine with 8GB non-upgradable too? Also, need dGPU?

any laptop < RM2000 , full screen 1080p. Mainly to watch youtube, and movies only.Maybe play old games occasionally
