Motherboard repair

When the motherboard fails, the computer becomes completely unusable, and the first thought of many is to buy a new motherboard or the entire computer. However, replacing the board (especially on laptops) is often extremely expensive or even impossible due to specific factory dimensions. Professional service and repair at the level of micro-components successfully solves the problem while saving up to 70% of the budget.

How to identify a fault on the motherboard?

Motherboard failures are among the most difficult to diagnose because their symptoms often resemble software, power, or RAM problems. Look out for the following clear warning signs:

• The computer shows no signs of life: You press the power button, but nothing happens - the lights don't light up and the fans don't spin.

• The computer turns on, but there is no image on the screen: The fans are running at full speed, you can hear the disc running, but the screen remains completely black without any signal.

• Random shutdowns and freezes: The device suddenly shuts down or freezes in the middle of operation, without a blue screen (BSOD) or error message, most often when it is under a little load.

• Smell of burning or visual damage: You have noticed a characteristic smell of burnt plastic and electronics from the case or laptop.

Most common interventions: Reballing, replacement of chips and capacitors

Modern services are equipped with advanced diagnostic tools (thermal cameras, oscilloscopes, laboratory power supplies) and specialized stations for soldering with hot air and infrared rays. Repairs on the board most often include:

• Replacing bloated capacitors: In older desktop boards, the capacitors responsible for ironing out the voltage swell and leak over time. Their replacement is quick, routine and successfully brings the board back to life.

• Repairing the voltage section (VRM stage): Burnout of tiny voltage mosfet transistors or controllers due to power surges is the most common cause of a complete dead board.

• Reballing and replacement of BGA chips: Due to prolonged overheating and poor cooling, small tin balls under the graphics chip (GPU) or chipset (Northbridge/Southbridge) crack. Reballing involves removing the chip, removing the old tin, placing new balls and re-soldering the board under precisely controlled temperatures.

• Corrosion cleaning after liquid spills: The most common intervention on laptops. Special chemical baths in ultrasonic baths remove corrosion and repair broken micro-conductors on the plate.
