Replacement motherboard for XPS 13 7390

This genuine Dell OEM motherboard carries part number JTF5T and board model LA-H931P. It arrives new with an Intel Core i5-10210U processor and 4GB of soldered LPDDR3 memory. The board is built for the XPS 13 7390 ultrabook chassis and supports M.2 NVMe storage.

Thermals and power in daily use

The 10th Gen quad-core CPU runs at a 1.60 GHz base clock and draws modest power for office workloads. Integrated Intel UHD graphics share the same thermal envelope, keeping fan noise low during web browsing and document editing. The compact 8 x 6 x 1 inch layout fits the original cooling solution without modification.

Behaviour under sustained load

Under continuous multi-threaded work the processor can reach 4.20 GHz turbo speeds within its thermal limits. Onboard 4GB RAM is fixed and not upgradeable, so memory-heavy tasks may hit capacity limits. The board is not suited for buyers who need user-replaceable memory or discrete graphics performance.

Questions sur cet article

How do I install the JTF5T motherboard in my XPS 13 7390, and which step do people often get wrong?

Disconnect the battery before removing the old board; many forget this and risk a short circuit when seating the new LA-H931P motherboard.

What maintenance or replacement will the onboard 4GB LPDDR3 memory need later?

The memory is soldered to the board, so it cannot be upgraded or replaced separately; a future capacity increase requires a full motherboard swap.

What limit appears first during sustained heavy workloads on the i5-10210U?

The ultra-compact chassis and integrated UHD graphics share thermal headroom, so CPU turbo clocks throttle early under prolonged load.
