LTE adapter for HP EliteBook

The YINGHUA T77H468 is an NGFF LTE adapter built to the 42x30x2.5 mm form factor. It provides FDD LTE connectivity through the 793116-001 module used in select HP EliteBook notebooks. The card adds mobile broadband to compatible systems without requiring a USB dongle.

Suits listed EliteBook models only

This module works with EliteBook 740 G2, 750 G2, 820 G2, 840 G2, 850 G2, 1040 G2 and Folio 9480m notebooks that accept the 793116-001 part. Builders repairing other laptops, desktops or tablets should look elsewhere because the keying and firmware are specific to those platforms.

NGFF interface and band support decide fit

The adapter uses an NGFF edge connector and supports LTE FDD bands 4 and 13 plus CDMA BC0 and BC1. If the target notebook requires a different M.2 key, a different LTE band set or a newer 5G module, this card will not function.

Questions about this item

Does the LTE adapter draw enough power to raise system temperature or fan noise during all-day use?

The module measures 42x30x2.5 mm and uses the NGFF interface, so its power draw is small and it adds no audible noise or noticeable heat.

Which antenna connectors and SIM slot must the laptop already provide for this module to function?

The host needs an NGFF (M.2) slot wired for WWAN with two antenna leads and a SIM-card tray; without those the card cannot connect to LTE networks.

Will the T77H468 work in an EliteBook 840 G2 that currently has no WWAN card installed?

Yes — the 840 G2 is listed as compatible and the module uses the standard NGFF interface with FDD LTE bands 4 and 13.
