HP ENVY x360 Convertible PC 15-aq155nr disassembly

Today I am taking apart an HP ENVY x360 Convertible PC model 15-aq155nr.

It’s likely this disassembly guide will work for some other models in the HP ENVY x360 Convertible line. Here are some of them:

15-aq001nx, 15-aq001na, 15-aq018ca, 15-aq050nw, 15-aq055na
15-aq118ca, 15-aq155nr, 15-aq166nr, 15-aq173cl

In order to remove the bottom cover we’ll have to remove all screws from the bottom. Two screws are hidden under the top left and right rubber feet.
You can remove the rubber foot with tweezers. It’s attached to the bottom cover by adhesive tape.

Start separating the bottom cover from the palmrest assembly using a thin case opener tool. Move the case opener along the side of the cover and wiggle to disengage hidden latches. Pry up the bottom cover a little bit.

Remove six screws securing the battery. Disconnect the battery cable from the motherboard.
By the way, the system battery (CMOS) can be easily accessed too. It’s a regular CR2032 Lithium 3V coin battery located just below the SD card reader.

Disconnect laptop battery

Remove the main battery. If you are replacing it, I would recommend using a genuine HP battery instead of third-party replacements.
You can find a replacement using battery model number MB04XL or HP spare part number 844204-850.
