![]() ![]() How would you go about this little hack? It somewhat reminds me of when Mike was hacking the Xray machine to remove the password. openin uefitool and find the VSS and find someones dump without pwd and can be copied in hexeditor. compare in hexeditor 2 files with Ctrl K / or verify in software programmer. likely wont read properly on the board as it sucks power from programmer. Another option would be to somehow get a copy of the flash file and try to program the chip without removing from the board. use asprogrammer or latest 1.33 or higher version china soft. If that works, sell the bios chip I bought on ebay. One would be to buy the replacement bios chip and perhaps lift one of the legs of the onboard bios while it is still on the board so that it won't function and use some micro grabbers and wire to link the replacement chip in to get the laptop to boot, then set the leg back down and try to reflash it. Back when PC motherboards had removable DIP flash chips, you used to be able to hot flash a chip by booting another computer, pulling the BIOS chip, dropping in the blank or donor chip and flashing the BIOS for the target motherboard with a flag to force the flash even if the model didn't match. Those chips from what I've seen, seem to use MOSI MISO SCK to access the chip which is good for me since that's something I'm somewhat familiar with programming AVRs. There are some people on ebay selling replacement bios chips for this laptop to remove the password lock for $25 and it appears to be just a small so8 serial flash chip. If that's the case, the password is flashed into the bios chip and HP says you have to replace the motherboard. According to HP the bios password can be reset by removing the main battery and clock battery and powering up off of the wall charger IF the extra security mode hasn't been enabled. I'm reasonably certain it isn't stolen because the seller is a refurbishing company that buys computers by the pallet from companies and has sold about 20 of this same model laptop without bios password locks. share you MiniPro TL866CS software free download link.
