HP EliteBook 45W Barrel Charger Price in Pakistan
Before HP switched to USB-C, most EliteBook and ProBook models from the G3/G4 generation (roughly 2016-2018) used HP's distinctive blue-tipped "smart pin" barrel connector at 45W — a thin rectangular tip with a small pin in the center that identifies the charger's wattage to the laptop. If your EliteBook 840, 820, or an equivalent-era ProBook 440/430 has this blue-tipped barrel port rather than USB-C, this is your charger.
The most common mistake is buying a generic barrel charger without the identification pin, or with the wrong physical tip size — HP's older laptops sometimes reject unrecognized adapters with a "non-HP AC adapter" warning on boot, or limit charging speed/performance as a safety measure. The second mistake is assuming any "HP charger" will fit; HP used several barrel connector generations across its lineup, and a slim blue-tip 45W charger will not physically connect to an older, larger rectangular HP barrel port.

How to verify you're getting genuine
- Check the tip closely — genuine HP smart-pin chargers have a slim blue-tinted rectangular tip with a small metal pin in the center; a tip without the pin will often trigger a "non-HP AC adapter" warning or reduced-charging mode on boot.
- Check the output printed on the brick — it should read "19.5V===2.31A"; this is standard for the 45W blue-tip line, distinct from HP's older 65W (3.33A) barrel chargers which use a similar-looking but not identical tip.
- Genuine HP bricks carry an HP part-number sticker and clean CE/FCC/UL certification printing — blurry or missing marks point to uncertified compatible stock.
- Boot the laptop with the charger connected — if you see an on-screen "non-HP AC adapter" or "90% performance" warning, the charger is either not genuine or has a damaged identification pin, even if it still delivers power.
- Confirm the barrel diameter physically seats flush and clicks in — a loose-fitting tip (even if it charges) risks intermittent power and accelerated port wear over time.
FAQ
What does the "non-HP AC adapter connected" warning mean, and is it dangerous?
It means the laptop's identification pin didn't recognize the charger's wattage signal — this happens with generic barrel chargers that lack HP's smart-pin ID circuit. It's not dangerous by itself, but HP may throttle CPU performance as a precaution since it can't confirm how much power is actually available. Using a genuine or properly ID-pinned compatible charger resolves the warning.
Can I use a 65W barrel HP charger on a 45W-rated EliteBook?
Generally yes if the tip size and identification pin match — HP's barrel chargers from this era negotiate wattage similarly to USB-C PD, so a higher-wattage charger with the correct tip will safely power a 45W-rated laptop. Always confirm the physical tip size matches first, since HP used more than one barrel diameter across different model years.
My EliteBook won't charge at all with the old charger — is it the port or the brick?
Test with a different known-good 45W blue-tip charger first. If charging resumes, your original brick has failed internally, which is common after years of daily coiling and uncoiling the cable. If it still won't charge on a known-good charger, the DC jack solder joint on the motherboard may have worn loose — a common, low-cost chip-level repair on this generation of EliteBook.
Do you stock genuine HP 45W chargers or only compatible ones?
Both — we stock genuine HP smart-pin 45W bricks (new sealed and tested pulls) and quality compatible alternatives with the correct identification pin, at a lower price point. We disclose the grade before you order.
What's the warranty and delivery on this charger?
New sealed chargers carry a 30-day replacement warranty; tested original (pulled) units carry a 7-day check warranty. Delivery inside Lahore is free and usually same-day; nationwide shipping is via TCS/Leopards. WhatsApp 0314 4000131 with your exact EliteBook model to confirm the correct tip.
