I did not get any response to my post (bios password for hp elitebook 2570p) does it mean there is no help?
Hi Patrick / Mazzif, I have read through many of your posts in the thread trying to obtain exactly the same results on the probook 640 G2. I have also come up against a brick wall it seems with the OTP regions on the bios. Did you manage to resolve these or was it a dead end? Please let me share with you what i have done up until now so that you can see if there is anything else i can try. The laptop i have was bitlocked which i thought might just be the harddrive, but it looks like that might also add protection on the bios also. Currently the bios is locked to boot only from the HD so i have no OS (bitlocked) however the bios should be intact which i can provide. The problem that i might have is that flashrom might not be able to read the 'one time memory' portions of the bios (which i think are currently necessary to boot the device). Bought a HP Probook 640 G2, boots and can enter bios (although password protected) OS is bitlocked and can't change boot settings to load OS from USB/Optical Removed the original bios chip (Macronix MX25L12873F) Read the original bios boot file in case i needed it. (using a raspberry pi & Flashrom). Then ordered the IC & Bios - the IC arrived was the Winbond W25Q128FV. Installed this and when pressing the power switch, I got nothing but a blinking orange light. So i removed the W25Q128FV and tried to read the bios.bin using flashrom but the chip was not recognised. I dug through the two datasheets and the W25Q128FV supplied has a '/HOLD' on pin7, This must be held high to activate the chip. Added the additional jumper and i was able to read the bios using flashrom first time. So i re-installed this into the probook (with a jumper for pin7) and this time the pressing the power switch turns on the laptop (and off) however... I did not get any display on the screen (backlight comes on), no audible sounds and the fan does start to spin (this winds up to maximum and stays there). Replaced the original bios without pin 7 and got the same black screen and spinning fan. (so pin 7 looks necessary) Connected up pin 7 and was able to boot once again (so the original bios boots every time, indicating hardware is all still working etc) Ordered a new Macronix MX25L12873F to see if i can replicate the same results from the existing bios chips. (I dont want to overwrite the existing MXIC) I programmed the new MXIC with the original bios i read - and got the black screen & fan spin (so i'm guessing this didn't read all the data) I programmed the new MXIC with the bios read from the W25Q128FV and still got the black screen & fan spin (so i'm guessing that this is now a bios issue and no longer a hardware problem) Finally replaced with the original untouched MXIC, and boots no problem. (I have kept this chip because it seems this is the only one that works and if written to i could loose whatever data is allowing this system to boot.) When reading the data, the MXIC (both) flashrom reads two chip names and also comes up with a warning about 'one time programmable' data which sounds like this might be the issue. If this section of the chip can't be programmed, then i might have to use the existing chip i have and test that with a new bios. I'm worried about overwriting information that i might not be able to retrieve again so this is currently a last resort. I do have the bitlocked HD (again untouched for the same reason) which i can try to recover the bios using 'Windows key & B' on start up - to see if this is possible. Then i can try overwriting this IC instead (this is my next step) Hopefully i have explained all the steps i've taken - and i'm sure that you can see they have been methodical and i really would like to try and solve this and hoping that you might be able to help. If you still have the working Bios from Badgenes would you be able to compare with what i have to see if i have managed to read all the data correctly because doing a straight read and write using flashrom has not worked. I can still obtain bios info but using the old chip - I have the serial number, SKU, UUID, Asset Number etc. Please let me know what you think and if i'm at a dead end and need to replace the mobo. Oh and i also have an SMC.BIN from HP however this didn't work for me and has pass a week (expiry) If i load an OS onto another harddrive will i be able to change the time to be able to retry this with the new MXIC? Any comments and suggestions very welcome and thanks for taking the time to rad this if nothing else! Cheers Steve
Hi, thanks for the offer to help - I did not know there was a second IC - is this usually visible, or does it likely require a complete dismantle? Yes these were the two threads i found that were most likely to help me solve the problem (and might help some others when hitting the same road block) Ok, So for obvious reason i have attempted the write to an identical IC, problem was that i had the same outcome as a different Model. No boot I have now actually solved the issue, but unfortunately i'm not going to be able to give a great answer for how i achieved it - perhaps you might know. I installed windows using an older laptop and swapped the HDD into the Probook, this booted windows (32 bit). (a success in my eyes, so that i didn't have to pay the £416 HP wanted for a new mobo). I needed 64bit installed, but had no other 64bit laptop. Installed 64bit vai a desktop machine, this blue screened after the windows logo (most likely a processor driver compatibility for instance?) So i cloned the windows install partition on the the HDD, leaving an additional partition for the windows install (upon install got a warning about partitions being in the incorrect order) Booted the laptop and installed windows (no blue screen). All good up until this point. This next bit is a little hazy, but after a few reboots? the laptop booted in 'Manufacturing Program Mode' I'm not sure how or why, it might have been down to a hardware change? But this obviously allowed me to change both the bios password and the boot order. I must add at this point i have no idea of the relation, but the solder joint to pin 6 which i believe to be the clock on this IC dislodged itself. (this actually prevents the laptop from booting, so i don't think it had relevance to the PMMode, and when replaced the PMMode was still there) Manufacturing Program Mode counted down from 30 to 0, and I was also able to install fresh windows from the hp cloud backup service. So a 100% success, however if i were asked to replicate the process i'm not sure if i could. Is there a way to enable the Manufacturing Program Mode? Cheers Steve

Hi every one, I bought two HP 9470m laptop in second hand. I tried logging in with the BIOS ADMINISTRATOR password but it locks me out. Is there a way to reset it? Please help.

Help, help, help!! I will paypal a reasonable fee to anyone that can send me the needed smc.bin file with good instructions.
nobody has the mystical smc.bin... what people do use is a software tool. or a hardware programmer to make backup of bios.bin
get cheap ch341a programmer and make backup.bin of the chip and i can clear it. after clear then flash back and done.
