Notebook Motherboard Repair in Bahía Blanca

Is your laptop not turning on, stuck on a black screen, or experiencing intermittent problems?

These are typical signs of motherboard problems, one of the most frequent repairs in our lab.

At CM Informática we perform advanced electronic diagnostics to identify faults in ignition circuits, GPU, BIOS, VRM, power supply and voltage lines.

We don't replace the entire board: we repair at the component level.

Genuine electronic repair (not a circuit board replacement)

“Don’t be swayed by hasty diagnoses. 70% of the motherboards rejected by other workshops in Bahía Blanca can be repaired in our lab.”

We have a laboratory equipped to work at the component level:

• Seamark ZM-R5860C BGA Station
• SVOD4 Programmer for BIOS and EC/KBC
• Microscope
• Microsoldering station (pencil and SMD)
• Digital oscilloscope
• Adjustable power supply
• BIOS Reprogramming
• Replacing MOSFETs, coils, capacitors, and diodes
• Track and pad reconstruction
• Voltage line measurement
• GPU/chipset diagnostics
• SPI and I²C communication between EC, sensors and peripherals

This allows us to recover motherboards that others consider lost.

Typical failures (MOSFET, BIOS, shorts, regulators) are repaired without replacing the entire board, at a much lower cost than a new motherboard.
