Hi there. Would a model with the 3 cell battery be easily user upgradable to the 6 cell battery? And what is the model number of the 6 cell battery?
i think its should can be upgrade to 6 cell battery
Chris,
Could you post part numbers from both 6-cell and 3-cell batteries please?
Hi, so, if I get a 3 cell battery, I can have and extra 2.5″ disk installed? Do you have any idea of a 3 cell battery life? Thanks!
I also see in your post that the image with a 2.5″ disk drive installed doesn’t have its connectors connected. Where is it located?
Hi thanks for the information. How did you copy the existing SSD OS/Data onto the new one?
How does it work upgrading the internal storage devices in the model with the 1 TB HDD, 32 GB SSD and 56 Wh battery? I see in the pictures you have just upgraded the M.2 SSD slot, and left the HDD alone. Is it a simple process to do this? What role does the HDD then play compared to the SSD? What if you were to upgrade the HDD with a 2.5 inch SSD? Sorry I’m a bit of a noob when it comes to PC internals!
