1. Removing the bottom cover
First of all, unlock and remove the battery.
Remove all screws securing the bottom cover. Pry up and remove the cover.
You can use a guitar pick or any other piece of plastic to split the case.
Under the bottom cover you can get access to the following internal components:
– Hard drive
– RAM slot
– M.2 slot
– Internal battery
– Heat sink and Cooling Fan
– Wireless card
– CMOS battery
2. Upgrade the RAM
The ThinkPad T450s comes with 4GB DDR3L-1600MHz RAM, but it’s also has a spare RAM slot.
In my case, I will add a Kingston 8GB RAM.
Here’s my new Kingston 8GB DDR3L-1600MHz RAM.
3. Upgrade the SSD
Here’s WWAN M.2 slot, I will install a Plextor 2242 M.2 SSD into the slot.
4. Upgrade the hard drive
The T450s comes with HGST 500GB 7200RPM hard drive. If necessary, you can upgrade to a larger capacity hard drive, or replace it with a 2.5″ SSD.
