Frequently asked questions
What is a BIOS bin file?
A BIOS bin (or dump) is the firmware image read from a laptop's EEPROM/SPI flash chip. Flashing a clean, tested bin is the fix for no-power, no-display and corrupted-firmware faults after board repair.
How do I request a BIOS file, schematic or boardview?
Post the exact board number (e.g. LA-xxxx, DAxxxx, NM-xxxx) in the BIOS & Schematics Requests forum. The community and our team respond fast — PRO members get priority handling.
Can you remove a BIOS or supervisor password?
Yes. We run dedicated sections for Dell (including unlock by service tag), HP, Lenovo/ThinkPad, Toshiba, Microsoft Surface, Apple EFI and Chromebook enrollment removal.
Are the files tested?
Files come from working repair technicians and the feedback in each thread tells you what was flashed and verified on real boards before you commit it to a customer's machine.
What do PRO plans include?
Unlimited downloads, priority handling of requests and a direct WhatsApp support line. See the PRO plans for details.
