Re: HP SpareKey issue with my HP Spectre x360
I can't thank you enough.
Is this HP's default Administrator password ? because it doesn't look like anything I've used in the past
Anyways, it worked perfectly well, and I was able to reset both the Administrator and Power On passwords successfully.
Thank you all for your help and support. This is a wonderful community.

Re: HP SpareKey issue with my HP Spectre x360
Hi @SMDFlea
I have an update to share.
So I used the HP Unlock Tool to generate an unlocked version of my bios.bin file. I erased the chip, wrote the unlocked bios.bin, and verified that the image was identical to the chip's memory.
This is what happened when I switched the laptop on:
- Caps Lock button blinks 3 times quickly;
- then laptop powers off and powers on;
- then Caps Lock button blinks 5 times slowly;
- then Caps Lock button blinks 3 times quickly;

Re: HP SpareKey issue with my HP Spectre x360
Hi @SMDFlea
Quick question, I'm trying my luck with the HP Unlocker Tool, and it seems to have successfully generated an unlocked version of my bios.bin file. Do I need to erase the chip using AsProgrammer first before writing the unlocked bios.bin file ? Or can I just overwrite the chip as is ?
ThanksLeave a comment:

Re: HP SpareKey issue with my HP Spectre x360
I just got my new CH341a and was able to run three read / verify tests to ensure that the chip is detected and read correctly. Here are the results:
Current programmer: CH341
ID(9F): C84017
ID(90): C816
ID(AB): 16
ID(15): 2020
AsProgrammer automatically identifies the chip as GD25Q64B, but as instructed, I manually set the chip type to MX25L6473E
1st Read
Execution time: 0:01:07
CRC32 = 0x45897089
2nd Read
Execution time: 0:01:07

Re: HP SpareKey issue with my HP Spectre x360
I tried resoldering all the pins on the ch341a hoping it would fix it, but it still doesn't work.
In fact, if I leaving my ch341a plugged in my PC's USB port for 20 seconds or more, it gets super hot, you can literally fry an egg on the pcb.
I don't want to damage my desktop's USB port or short its motherboard. I'll wait for the new ch341a to arrive before I continue with the BIOS dump.
I can't thank you enough for all your help and support.
I'll report back once I've successfully...Leave a comment:

Re: HP SpareKey issue with my HP Spectre x360
Thank you for the instructions. I just found out my CH341A is damaged. I ordered another one which should arrive in a week. Will post my dump as soon as I get the new CH341A adapter. Do I need to de-solder the chip prior to dumping it ? Or can I just dump it using the Pomona Soc8 clip while it's still soldered to the motherboard ?...Leave a comment:

Re: HP SpareKey issue with my HP Spectre x360
Ok great. So we've been able to identify which chip needs to be dumped. So now, I just need to attach a dump of this chip ? Or are there other chips I need to dump as well ?Leave a comment:

Re: HP SpareKey issue with my HP Spectre x360
Here are hi res photos of all the chips on the motherboard excluding the CPU.
The only chip I could find that is relevant to this is the Winbond chip. There are no other Winbond chips on it....Leave a comment:

Re: HP SpareKey issue with my HP Spectre x360
I did check my bother board again, and this is the only chip that shows that kind of number. I even scanned my motherboard and attached it for reference. Unfortunately most of the numbers on the chips are unreadable. But I'll follow up with some Hi Res shots of all the chips on it hoping it would help....Leave a comment:

Re: HP SpareKey issue with my HP Spectre x360
HI @SMDFlea
I don't recall creating an HP SpareKey USB stick for that purpose. I don't have one. When you say the largest bios chip, which chip would that be ? I've taken photos of what I thought are the relevant chips, but when doing some research, the "Winbond 25Q80DVIG" comes up as being the BIOS chip.
I've attached some photos to give you an idea. If you want me to take more photos of different chips, I can certainly do that.
I'd really appreciate your advice.

HP SpareKey issue with my HP Spectre x360
Hi there,
I've come across an issue with my HP Spectre x360 13-ac033dx laptop after clearing the "Administrator" and "Power On" passwords. Originally I had the same password for both and that worked fine, until I decided to go into the bios and clear them. I'm sure I cleared both passwords as well as save my changes on the bios setup screen, but for some strange reason, my laptop continues to ask for a password and now refuses to accept my earlier password no matter what I do.
The laptop does not produce any halt or error code, instead it asks for...Last edited by tansoftware; 05-16-2020, 07:43 PM. -

Hello everyone,
My name is Terry, and I'm from Ottawa, Ontario, Canada. I'm an electronics and computer hobbyist and a dentist by trade. I started programing in assembly at the age of four, and by the age of 6, I was taking every single electronic device in my parents' house apart and putting it back together again.
