EliteBook 840 G3/G4 Heating Up — Fix It for Rs. 3199
The HP EliteBook 840 G3 and G4 represent HP's 6th and 7th generation Core i5/i7 business ultrabook lineage — still widely used across government offices, banks, and corporate fleets in Pakistan. After four or five years of full-time use, the cooling fan is often the first component to show wear. Grinding noise, constant full-speed running, or thermal shutdowns at modest CPU loads are all signs the blower bearing has failed. The HP EliteBook 840 G3/G4 Cooling Fan at Rs. 3199 is the direct-fit, bench-tested replacement.
This is the HP EliteBook 840 G3/G4 fan price in Pakistan 2026 — a cost-effective fix that extends the machine's life by years. N.N Laptops, Hafeez Center, Gulberg III, Lahore bench-tests every unit before listing. Customers from Lahore, Karachi, Islamabad, Rawalpindi, and Faisalabad place orders knowing each part has been individually checked for bearing noise and RPM accuracy before dispatch.

Compatibility Details & Installation
This fan fits the HP EliteBook 840 G3 (product numbers T9X21EA, V1H24US and similar) and EliteBook 840 G4 (1GE43EA, Z2V49EA and similar). The EliteBook 840 G3 HSPA variant has an additional antenna cable routed alongside the fan duct — unhook it before lifting the fan assembly to avoid damage. The 848 G3/G4 (rare, with 4G modem) uses the same fan body but has an extra antenna connector. To install: remove six bottom-panel T5 Torx screws, disconnect the battery connector, unplug the 4-pin fan header, undo two M2 mounting screws, extract the assembly, apply fresh thermal compound (the G3/G4 uses a standard CPU die — no pad replacement needed), seat the new fan, and reassemble. HP BIOS validates the new fan automatically on next boot. Job typically done in 20-25 minutes.
