Fully rugged 13.1" laptop for field work

The Panasonic Toughbook CF-31 MK4 is a fully rugged notebook built to MIL-STD-810G and IP65 standards for operation in harsh environments. It runs Windows 10 Pro on a 2.7GHz Intel Core i5 processor with 4GB of DDR3 memory and a 256GB SSD. Integrated Verizon 4G LTE provides mobile connectivity where Wi-Fi is unavailable.

Digitizer pen and power adapter included

A digitizer pen is supplied for precise input on the 1024 x 768 XGA touchscreen, which is designed for sunlight-viewable readability. The bundled AC power adapter ensures the system can be charged immediately upon deployment. No optical drive is fitted, reducing moving parts and potential failure points in the field.

Single-core processor limits multitasking

The CPU is a single-core 2.70GHz Intel Core i5, which restricts performance in multi-threaded workloads and concurrent applications. Buyers who need more processing threads for modern multi-tasking or virtualisation should consider alternative platforms. The 4GB DDR3 800 memory configuration is fixed at 2GB x 2 modules.

Questions about this item

How do I replace the two 2 GB DDR3 800 modules when I need more memory?

The laptop uses two 2 GB DDR3 800 SODIMMs; remove the bottom cover, release the clips on each slot, swap in matching DDR3 800 modules up to the board limit, then reassemble.

What limits continuous performance first — the single-core 2.7 GHz i5 or the 4 GB DDR3 800 memory?

The single-core 2.7 GHz i5 reaches full utilisation before the 4 GB DDR3 800 memory becomes a bottleneck during sustained workloads.

How loud does the fan get and how hot does the chassis feel after an 18-hour shift on Verizon 4G LTE?

The MIL-STD-810G tested chassis stays within safe skin-temperature limits and the fan runs at a low, steady rpm during an 18-hour shift on Verizon 4G LTE.
