Frequently Asked Questions
help What happens if a BIOS update fails?
If a BIOS update is interrupted, the motherboard firmware gets corrupted, rendering the laptop 'bricked' (powering on with a black screen and fan spinning). We flash it using an external programmer.
help Do you replace laptop CMOS batteries?
Yes, we swap dead CMOS coin batteries (starting from ₹999), which resolves date/time errors and checksum check failures on startup.
help Can you remove a forgotten BIOS password?
Yes, we reprogram the BIOS EEPROM chip to clear passwords and security locks, restoring full access to boot configurations.
help Why does my laptop boot directly into the BIOS screen?
This happens when the motherboard cannot detect a bootable storage drive, indicating bootloader file corruption, a damaged SSD/HDD, or incorrect UEFI settings.
help How long does a BIOS flashing service take?
De-soldering the BIOS chip, reprogramming it on an EEPROM writer, and re-soldering it to the motherboard takes approximately 2 to 4 hours in our lab.
