AC adaptee not charging my HP zbook 15

[h4k1m]

Hi,

I have a HP ZBook 15 mobile workstation (G1) and its 120W charger doesn't seem to work. The power button, the caplocks button's light and the power light on the front start to blink when I plug the ac. I've found a video on YouTube saying that the blinking means the charger is faulty (although it used to work before).

My question is which charger should I buy to replace my current one? Should I get a 150W charger like the HP 150W smart AC adapter

Depending on the configuration of your machine, you may need up to 200W charger (other configurations use 120W or 150W). What is part number of the original 120W charger ? Please turn its back to find out its p/n

Regards.

Thanks for your answer.

My old charger's part number is: 644699-003

I've ordered the 150W slim smart AC adapter (4SC18AA#ABB) yesterday, as I saw it mentioned on my laptop's page with other supported chargers (with the 200W one).

Could you please let me know if the charger I got is supported?

Thanks

Hakim.

I've ordered online the 150W charger (4SC18AA#ABB), do you think it's going to be compatible with my laptop.

Thanks
