HP EliteBook 840 G8 Battery Replacement Cost Pakistan
The EliteBook 840 G8 (11th-gen Intel, launched 2021) sits in the last generation before HP redesigned this line's internal battery for the G9, which matters more than it sounds — the G8 and everything before it (G5-G8) share a common 56Wh 3-cell pack and connector, while G9 onward changed both. If you're quoting a battery online and the price looks off, it's often because the seller quoted the wrong generation's part. Most people here have a corporate-issued or corporate-surplus 840 G8 that's 2-4 years into daily use and noticeably losing runtime.
Pricing in Pakistan is Rs. 3,800 – 5,000 for a Tier-1 OEM-equivalent 56Wh pack, or Rs. 5,000 – 6,000 for a genuine HP-branded battery. This is one of the most straightforward replacements we do at Hafeez Center — standard HP connector, backlit spill-resistant keyboard sits above it undisturbed, and no adhesive or e-EPROM-style authentication lock to work around. We confirm your exact G-generation (via the sticker on the base or the HP support site with your serial number) before ordering, since a G9 part won't fit or connect correctly on a G8.
Cost breakdown
oem
- price
- Rs. 5,000 – 6,000
- notes
- Genuine HP-branded 56Wh battery (HSTNN/BSN-series part numbers). Preferred for corporate assets where IT policy tracks genuine HP parts, or if you want the battery to match under HP Support Assistant's hardware inventory.
compatible
- price
- Rs. 3,800 – 5,000
- notes
- Tier-1 OEM-equivalent 56Wh 3-cell pack with the standard HP connector used across G5-G8. Self-calibrating like the original — shows 100% health immediately after fitting and settles in over the first two charge cycles.
labour
Included in the price above — no separate callout or labour fee. Bench time: 30-90 minutes (screw-mounted pack, no adhesive).
warranty
15-day repair warranty on the labour plus a 30-day battery warranty on the new pack itself — if it fails through no fault of your own (drops, spills and physical damage excluded) within 30 days, we replace it again at no charge.
Signs your battery needs replacement
- ▲Runtime has dropped from the original full-workday rating to 1-2 hours or less
- ▲HP Support Assistant's battery check reports the pack has failed or shows health well below the “Good” threshold
- ▲Windows shows “Consider replacing your battery” with a battery warning icon
- ▲The battery percentage reads inaccurately — shows 100% for a few minutes after unplugging, then drops fast
- ▲The base near the trackpad feels slightly raised or doesn't sit flat — check for swelling, common once a 3-cell pack of this age nears end of life
Turnaround time
Walk-in
Same day for walk-ins — most Windows business-laptop battery swaps take 30-90 minutes once you approve the quote, because the pack is screw-mounted rather than glued.
Courier from other cities
5-9 working days round-trip from Lahore, Sialkot, Gujranwala, Faisalabad, Islamabad, Rawalpindi or Sargodha; 7-13 working days from Karachi, Multan, Peshawar, Hyderabad, Abbottabad or Bahawalpur; 9-16 working days from Quetta or Sukkur. That covers courier there, free diagnosis within 24 hours of arrival, the repair itself, and courier back — we confirm your exact date on WhatsApp once diagnosis is done.
Frequently asked
Can I replace the EliteBook 840 G8's battery myself?
Yes, this is one of the easier laptops on this list to self-service — the bottom cover comes off with standard screws, the 3-cell 56Wh pack sits in an open bay with no adhesive, and it's held by two screws plus a single connector. As long as you confirm you're buying a G5-G8 pack (not a G9/G10 part, which uses a different connector), installation is genuinely a 10-15 minute job.
Does this repair void any remaining HP warranty?
If your 840 G8 is still under HP's original business warranty (commonly 3 years on-site for EliteBook units), check coverage via HP Support Assistant or hp.com/support with your serial number before using third-party repair. Most G8 units in the used/repair market are already past that window, and our own 15-day repair plus 30-day battery warranty applies instead.
How do I check battery health and cycle count on the 840 G8?
HP Support Assistant (usually preinstalled) has a Battery Check under My Devices > Component Tests, showing pass/fail plus a health percentage. Windows' powercfg /batteryreport also works and gives Design Capacity vs Full Charge Capacity with a 30-day history. Either free method gives you a real number before you spend money on a replacement.
How do I know if I have a G8 or a different generation before ordering?
Check the sticker on the bottom of the laptop (it lists the exact model, e.g. ‘HP EliteBook 840 G8 Notebook PC’), or press Esc at startup then F1 to view System Information in BIOS. If you're not sure, WhatsApp us a clear photo of the bottom sticker or your serial number and we'll confirm the generation and correct part before you order anything.
Is it worth replacing the battery, or is the 840 G8 close to end of useful life?
Worth it in almost every case — an 11th-gen Intel business laptop still has years of useful life ahead for office work, and a Rs. 60,000-80,000 used 840 G8 getting a Rs. 3,800 – 5,000 battery is roughly 5-7% of its value. It only makes less sense if the laptop has multiple simultaneous faults or you specifically need features (newer WiFi standard, longer future OS support) that a newer generation offers.
