Questions about this item

How do I install the 73TVN board in a Latitude 3390 2-in-1, and which step do people get wrong?

Remove the battery first, then disconnect the display and antenna cables before unscrewing the old board. The step most often missed is forgetting to unplug the coin-cell battery connector, which can short the new 73TVN board on first power-up.

What maintenance or replacement will the on-board i5-8350U 1.7GHz processor need later?

The CPU is soldered to the 73TVN board, so it cannot be replaced separately. Maintenance is limited to renewing thermal paste on the heatsink every few years and keeping the fan vents clear of dust.

What limit appears first when the 73TVN board runs sustained loads?

The 1.7GHz quad-core i5-8350U hits its thermal ceiling first; the slim 2-in-1 chassis cannot dissipate heat fast enough, so clocks throttle down after several minutes of full utilisation.
