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
