HP PROBOOK 4530S HANG ON HP LOGO...
hi, i am in deep problem right now and some really helpful insights is really appreciated. the hp probook 4530s was first having some viruses, and i decided to update it to windows 10 pro,i did not format it, i just install the new windows on top of windows 7 so i would not lose the files.. it was a success, everything is working, but then after a week, it won't open, it only hangs on hp logo, with a message on the bottom left press esc with some message i forgot. but it just hang on that message, until you press power button for a few seconds to turn it off, then nothing again.
so i search on google and ask some tech friend, he said it might be the bios. it needs to be reprogrammed. so i decided to try something stupid. i have an old dead hp laptop, i took the bios chip from that even though it did not match with the bios chip of the probook 4530s, i still solder it there. and then the laptop died. no power, with only light orange and white on the charging port.
even if i put the old bios chip, it did not power back to the hp logo...
anyone could help me what could i do, some schematics or anything..
i cannot afford a board replacement so board replacement is a no for me... any repair thing could help. please. thanks
