Re: HP 8570w BIOS Chip de-/resolder
scrape away the trace until you get down to the copper,then solder a thin wire onto it. Solder the other end onto the legs of the bios chip .Attached FilesComment

Re: HP 8570w BIOS Chip de-/resolder
Embarassing as it may be but i already threw it in the trash can out of pure frustration of how i messed the pcb up. For what its worthi would really like to know what i did wrong with the copper braid, so that at the very least i can learn from my mistake.
When i tried to clean the pads with the copper braid, i put my iron to 350°C and started to wiggle at those pads but immediately the copper braid was kinda stuck and glued to the pads and when i finally removed it, the pads were gone too.Comment

Re: HP 8570w BIOS Chip de-/resolder
Apply fresh solder to pads. Use higher temperature, more flux and add fresh solder to the wick(braid).
But it is always easier to just use hot air and not even mess with the braid.Comment

Re: HP 8570w BIOS Chip de-/resolder
when wiping u must feel that braid is loose. if u feel just a little resistance u must stop and apply more heat or longer heating.Comment

Re: HP 8570w BIOS Chip de-/resolder
Dumb question possibly, but is there any way to have some type of connector to let you reprogram the chip without removing it from the board ?Comment

Re: HP 8570w BIOS Chip de-/resolder
Of course, they exists Like the Pomona SOIC8 clip, but it isn't recommended to use them except you're always Checking for corruption after Reading the bin.
I Challenged this before and it isn't so nice to read a corrupt BIOS Out of the SPI FLASH without knowing it. Since then i'll either Check the Image or desolder it.Comment

Common SPI bios chip programming Questions and Answers
----------------------------------------------------------
Q: I have a bios request,i can`t post my backup as i can`t read from the chip.
A: If you can`t read from it how do you expect to write to it ?.
Q: Why is my bios chip unreadable ?.
A: The programmer is faulty or has a worn or broken zif socket.
The USB cable is frayed,connector pins worn or some other physical damage.
Not enough amperage or voltage to power the programmer properly.

Hello Community,
I recently tried to change the Batterie on my Omen by HP Laptop 17 an104ng and after putting in the new batterie ([Batterie Link](https://www.amazon.de/7xinbox-17-AN0...&keywords=16%2... -
Long story short:
- dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
- gave the computer to his son a couple years later
- son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
- too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)
(seems like the story was not that short)
He used alligator clips to read the chip. No luck reading it. Removed chip and placed on a SOC-8... -
Hello, first of all, excuse me, I am using the translator, English is not my native language.
I have a Lenovo ideapad 330S - 14IKB laptop.
The tablet did not recognize me when I connected it, so I checked the device manager and I realized that there were many with the exclamation mark, so one by one I began to update their drivers until the sign disappeared of admiration, I even updated the BIOS, and the laptop rebooted normally and worked, so far so good, but the tablet still did not recognize me, I read on the internet that it could be due to a... -
My pc updated bios through Windows Update and I was greeted with BLACK SCREEN WITH CPU FAN MAX SPEED. I don't think there is even a screen signal, because it triggers my monitor for a couple seconds and then the monitor turns off. I tried the other outputs as well.- I tried clearing bios, resetting bios, removed the CMOS battery, removed m.2 ssd, wifi, and ram. Still black screen with CPU fan blasting.
- I tried using the Lenovo BIOS CD and BIOS USB, but neither worked. At least I couldn't get anything to work.
- I could only locate two chips that look like bios chips. Could someone verify this
