On the Probook 4530s models that I worked on there was a button on the top-right (there should be two together) to enable wireless connections. Make sure the light is blue. Also on the previous 45xxs there was also a button in the front of the laptop or around the corner on the left. HP might have moved it there when they made a new revision.
Lastly,
HP's Connection Manager allows you to click and disable the radios separately. You'll definitely have it installed so it might just be disabled. Also check in Computer Management to see if it isn't disabled in there. If its not disabled and does register then all that's left is
faulty drivers or faulty hardware.
Also, can you take a picture of your keyboard?
ACQ is the code for any of HP's products sold in Russia, which is a bit weird. Yours might have been stock that HP swapped around when they were doing their product refresh. SA products normally have EAQ at the end.
