If the fan spins but there is no display, the BIOS may be corrupted. The main BIOS file is typically 4MB .
After compiling data from community repair logs, here are common problems and verified solutions for the LM495 MB 11269-2.
When the laptop shows no signs of life, the primary power rail (often labeled as VIN or +19V ) must be traced. The schematic helps locate the initial DC-in MOSFETs and the charging IC. Technicians check if the 19V rail is shorted to ground or if it fails to pass through the secondary isolation MOSFET due to a faulty gate signal. 2.
