What we repair on the HP ProBook 455 G9
Screen replacement
Cracked, flickering or lined 15.6-inch screens are replaced with a matching panel. Where the picture comes and goes as the lid moves, we check the display cable and hinges first.
Price confirmed before work starts
Memory upgrade
Most configurations of the HP ProBook 455 G9 have SODIMM memory slots, so memory can be increased. We check what is fitted and the maximum the board supports.
Windows repair and reinstall
The HP ProBook 455 G9 shipped with Windows 11. We repair start-up faults, reinstall Windows cleanly with your files kept, and remove malware.
Battery replacement
We replace the internal battery and check the charging circuit and adapter at the same time. On a 2022 machine a worn battery is the likely cause of short runtime, and we measure its capacity before recommending anything else.
Price confirmed before work starts
Charging port and power repair
Depending on the configuration this charges through a round socket, USB-C or both. We test the adapter, the port and the charging circuit to find which has failed.
SSD and storage upgrade
The HP ProBook 455 G9 has an M.2 slot and, on some configurations, a 2.5-inch bay. Machines that shipped with a hard drive are much faster once moved to an SSD.
Price confirmed before work starts
We also carry out keyboard and trackpad repair, motherboard repair, liquid damage repair, overheating and fan repair, hinge and casing repair, virus removal on the HP ProBook 455 G9, along with USB, HDMI and audio port repair, Wi-Fi and Bluetooth card replacement, webcam and speaker faults, BIOS password removal with proof of ownership and data transfer to a new machine.
Notes from the workshop
- Hinge and lid-mount wear shows up on older 450 and 470 models.
- A forgotten BIOS administrator password usually needs board-level work, with proof of ownership.
- ProBooks are straightforward to service, with replaceable batteries, SSDs and memory on most generations.
Data recovery from the HP ProBook 455 G9
The SSD in the HP ProBook 455 G9 can be removed and imaged on our own equipment, so files can usually be recovered even when the machine will not start. Recent Windows machines often have device encryption or BitLocker switched on. If so we will need the recovery key, which is normally saved in your Microsoft account.
