Has anyone who own ExpertBook B9 model came across the bottom cover somehow dented and forms bubble after sometime?

Mine is 3 years plus and sort for realize recently that the bottom is uneven and formed bubble. Wonder if it was due to the heat?

hmm, could it be the battery bloated?

I thought it as first too but the dent is not only at where the battery is, it's the entire bottom cover surface.

well, i think the only way to find out is open it up and see...

Just opened bottom cover and battery is normal.

anything unusual under the hood?

Nothing at all, very strange to see the bottom cover become dented for no reason.

hmm, if no weird things going on, then maybe not a concern...

still, how's the system / CPU / GPU temperature when running?

plastic part for electronic commonly use PC/ABS and the melting point is above 200c,
deform caused by heat from the system is unlikely, unless the device was put constantly under heat stress aka from direct sun light, sun light can degrade plastic.

another possibility is the bottom already deformed since bought due to molding cosmetic defect.

Nothing concerning, all running normal.

That make more sense

My old asus laptop had this issue as well. Forgot which model was it but I guess it was heat that caused the bubbles and deformed bends. Wasn't really bothered about it coz it didn't really affect anything like performance issues or overheating. Worth a try to contact Asus service centers if you are concerned.

I believe this is eligible for warranty claims. Give it a try.

Tried calling them but I was only noticed it 1 week after warranty ends! So basically they told me I need to pay for the inspection and replacement of the cover

I was about to but was only realize the bump a week after the warranty ends. So Asus told me I need to pay for it.

Sent to Asus Authorized Service Center and get the bottom case replaced. Now it's good as new, cost me RM 259 as it's out of warranty.

I notice that CPU/GPU temp is sometime shoot up to 70 degrees and it's damn hot at fan area

asus laptop cooling had always been an issue in the history

I have buy a mini desk fan to keep it cool when working. Might even consider changing to Dell XPS

always dell latitude.. not XPS.. latitude build to last.. XPS for flexing..

DELL i can say i m taikor in this forum.. keke

Do use cooling pad as laptops these days are too thin & compact for good cooling. Coolermaster U2/U3 has configurable fans to blow at the hottest spots.
Plus dont use on laps or carpet or lay on uneven places. Turn on battery saving features even if plugged in as it lower speeds (thus heat) and ramp if needed.

Though I'm impress with latitude performance but the design somehow thick me off especially for someone like me who travel often Need lightweight laptop

I'm thinking of getting one but might change laptop soon so still thinking whether should I get now or later.

latitude 7000 n 9000... light n more robust than xps

Now latitude 9440 have my attention

Get now lar. Can also use for the new laptop when you decide to buy wat. If powerful new laptop will likely have heating issues too

Can bump up to RM12k with all the additional hahaha

I am about to haha, 90% will got with Dell again this time like my Vostro version before this ASUS laptop

the 1 i quote almost max spec de.. 32gb its max.. i dell dfo distributor n commercial reseller..

platinum tier pricing can giv u

Most likely is Manufacturers are going for Biodegradable plastics.

Would recommend you avoid those Asus and Acers.

I would advice do more thorough study on reviews b4 buying. Good start is Notebookcheck where they also consider thermal issue & heat spots.

Lesson learn, no more asus despite the good looking design and lightweight marketing point.

I used Dell Vostro before for almost 7 years and never had any issues except the wifi strength which Dell replaced a new unit for me FOC!

Guess it's time back to Dell again

Trusting a brand to continuously making quality stuff isnt such a good idea, but its up to you. Id still advice you to go thru reviews so that you understand its quirks and you are happy with it before you take the plunge.

Guess I could not agree with you more, thanks for the advise.
