Worth noting that the left panel appears to be secured by 3 clips at the bottom edge on the 3650 model, is it the same on this one? Slide a lifter in between the bottom panel and the lower edge of the left side panel to free and it should just lift off.

NOTE OF CAUTION: pay attention if you are attempting any kind keyboard assembly component or battery swap out. I have just taken apart a 13.5 and pierced one of the battery cells (%#*@) during a frustrating and tedious attempt at replacing the trackpad. Note of caution; the battery cells are adhered to the removable panel and are easy to pierce during the disassembly process. The reason for this is its proximity to the edge and the amount of adhesive applied. Also worthy of note the centre of panel at the top of the trackpad is seriously stuck down - PATIENCE is the key, flexing and using wide beveled plastic tools to seperate the adhesive bit by bit.

Once again MS have screwed users over with a virtually unrepairable laptopI scrapped 3 on behalf of users that could not be repaired and advised them against purchasing this type again. It looks like that advice is going to remain in place for this model. Such a shame MS taking a leaf from the worst of Apple behaviour and producing yet more techno junk with limited lifespan (2yr average in my experience). The worst of is the sheer indulgent price of these systems.
