Customer give the notebook another repairshop before bringing to me.Other shop could not find fault and messed up power and charge chontrol ic s and couple mosfet with using heat station . I am found the faulty part, RT8205 vref pins 0.22uf cap short and I change the cap and I check and fix other bad soldering parts.I am plug the dc cord but only white dc led blinks and no main dc in circuit.then I found KBC_EC not drive the mosfets.I suspect the bios ic because it also soldering couple times before.I read the bios but only in updates 68azz.bin written before by stupid other repairmen.I am found the net 3 bios file different sites but all identical (one site says 4520s with ati gpu).I write the bios then solder back.Notebook work but no screen coming ,only backlight comes and brightness control work.Bios F10and CTRL+ALT+DEL also work .External monitor not work.I need onboard graphic models full 4mb bios file.I am promise if you send file , ı use dmi tool and change my serial ,mac address ,etc.Sorry for my poor English, thanks.
