Questions about this item

How do I upgrade the RAM on this Latitude 5420 and which slot do people forget?

The laptop supports up to 32 GB of DDR4 memory. The 16 GB module occupies one of two SO-DIMM slots; install the matching stick in the empty slot and seat it firmly until the clips click.

Which components will need replacement first on this 5420?

The 512 GB NVMe SSD and the internal battery are the only user-replaceable parts that wear out. The soldered CPU and integrated graphics cannot be swapped, and the 16 GB DDR4 module lasts the device lifetime.

What thermal limit appears first when the i5-1145G7 runs sustained loads?

The integrated graphics share the processor's 8 MB L3 cache and cooling solution, so the CPU hits its thermal throttle point before the GPU becomes a separate bottleneck during prolonged workloads.
