You’ve bought a second-hand HP ProBook and don’t know its service history, or the laptop has started behaving strangely? Diagnostics reveal the device’s real condition. Repair usually takes 1–3 working days.
In short: ProBook, as HP’s mid-range business series, very often comes from the second-hand market, where the laptop’s service history is usually unknown. We measure real power draw with a lab power supply and check the drive, cooling system and motherboard before proposing a repair.
Our experience with HP ProBook
We’ve carried out diagnostics on 2 HP ProBook laptops. This is HP’s mid-range business series, also very often coming from the second-hand market, just like the higher-end EliteBook class.

ProBook — why diagnostics are especially valuable here
Since many ProBooks reach the second-hand market after corporate use, buyers often have no idea how the laptop was previously used and serviced. Measuring real power draw shows the device’s actual condition, instead of relying solely on age or external appearance, which can be misleading with business laptops.
