Try a full power refresh. You never know it may work.
I realize that you said that you did remove the power source and pressed the power button but sometimes it is necessary to remove the RTC battery (Real Time Clock) from the motherboard as well to reset the BIOS back to its default state.
Here’s the procedure:
a). Disconnect the charger from the laptop if connected.
b). Remove main battery from the laptop.
c). Remove the RTC battery from the motherboard.
Here’s the [link|http://h10032.www1.hp.com/ctg/Manual/c03054480.pdf|maintenance and service guide] for the laptop. (couldn't find one for a 4530 so hopefully the 's" model is the same) Go to p.91 to view the necessary pre-requisite steps and then the procedure to remove the RTC battery. Unfortunately with your model you will have to remove the motherboard to access the battery.
When the battery is removed measure its voltage. If it is <2.6V DC replace it. The part number is 449137-001. Search online using the part number ''only'', to find suppliers of the part.
d.) Reconnect the RTC battery (or its replacement).
e). Reverse the above steps to re-assemble the laptop.
f.) When the laptop is completely re-assembled, connect the charger and try to turn on the laptop.
If it starts OK there may be a message about the date and time being incorrect. This is normal as the BIOS has been completely reset back to its default settings. Once the date and time have been adjusted the message won’t appear the next time that the laptop is started.
If you had previously changed any user defined settings in BIOS to suit whatever specific hardware configuration that you had for the laptop, then these will have to be set again.

If it does work you can always try upgrading the ram to 8GB (2 x 4GB PC3-10600, 1333-MHz, DDR3) as Win10 will work OK with that much ram
