GPU (Graphics Processing Unit)
The chip responsible for rendering images to the display. GPU failure causes no display output, visual glitches, or crashes during graphics-intensive tasks. On laptops, replacement usually means board repair or BGA rework.

The GPU is the chip responsible for processing and rendering visual output. Without a functioning GPU, the laptop cannot produce any image on screen or an external monitor.
On laptops, the GPU is soldered directly to the motherboard as a BGA package — it cannot be removed and replaced like a desktop graphics card. GPU failure requires board-level BGA rework or full board replacement.
A separate dedicated graphics chip (NVIDIA GeForce, AMD Radeon). Found in gaming laptops. More powerful but generates more heat. Most GPU failures occur here due to thermal stress.
Examples: RTX 4070, RX 6600M
Built into the CPU — shares system RAM. Found in everyday laptops. Less powerful but uses less power. Integrated GPU failure typically indicates CPU or board failure.
Examples: Intel Iris Xe, AMD Radeon 780M, Apple M-series
- Artifacting — coloured squares, flickering patterns, random pixels
- No display output — blank screen on both internal and external monitors
- Screen goes black during gaming — GPU failing under load
- Blue screen errors — GPU driver crashes causing system instability
- Faults that worsen as the laptop heats up — classic BGA solder joint failure pattern
Can a laptop GPU be replaced?
Not like a desktop GPU. Laptop GPUs are soldered BGA chips. Repair options are BGA rework (reflowing or reballing) or full board replacement.
How do I know if my laptop GPU has failed or if it’s just a driver issue?
Driver issues go away after reinstalling drivers. Hardware GPU failure produces persistent artifacting or black screens not fixed by drivers. If symptoms persist in Safe Mode or BIOS, the hardware has failed.
Is GPU repair worth it on an older gaming laptop?
Depends on age and market value. For a laptop 3–5 years old with good resale value, BGA rework is often worth it. Free diagnosis gives you the information to decide.
Can I use a laptop with a failed discrete GPU?
Sometimes — if the laptop has an integrated GPU, it may be possible to disable the discrete GPU in BIOS and run on integrated graphics for basic tasks.
Free diagnosis to confirm GPU fault. BGA rework where viable. Honest assessment of repair vs replace.
