Laptop repair terms sound technical, but most of them describe something simple. An IC is a small chip on the board. BGA means a chip held on by a grid of tiny solder balls. Reflow melts those balls so the joints reconnect, and fabrication means rebuilding a broken piece of the casing. Knowing what a word means lets you ask the right question when a shop says your laptop needs "chip-level work" or "a new board".
This glossary is grouped by the part of the laptop the word belongs to: the board, power, the screen, the body and storage. Each entry says what the term means in plain words and what to ask a technician when they use it. It is written for owners, not for technicians, so it keeps the detail to what helps you decide.
Board and chip terms
Motherboard. The main circuit board. The processor, memory, storage and ports all connect through it. Apple laptops call theirs the logic board. When the board has a fault the laptop may not power on, may not show a picture or may restart at random.
IC (integrated circuit). A small chip on the board with a single job: charging, power control, audio, the keyboard controller and so on. "IC repair" means finding the one that has failed and replacing it, which usually costs less than replacing the entire board when it is possible.
Board-level repair. Repair that works on the board itself, instead of swapping the whole board. The technician finds the failed small part, such as a chip, a coil or a capacitor, and replaces it. Some shops call this "chip-level repair". It takes longer than a part swap, which is why board-level work takes two to five days with us. Graphics chips are a separate case: we do not reball or replace a graphics chip.
Short circuit. An unwanted path for current. On a laptop it often shows up as a machine that will not power on, a charger that cuts out, or one spot on the board that gets hot. Finding the short is the first job in many board repairs.
Power rail. A set voltage line on the board that feeds one group of parts. If a rail is missing, whatever it feeds does not work, which helps the technician narrow the search.
Capacitor. A part that stores and smooths electrical charge. A capacitor that bulges or leaks has failed. Our page on bulging capacitors explains the repair.
BGA (ball grid array). A way of mounting a chip so that tiny balls of solder under it form the connection to the board, with no visible legs. Processors, memory controllers and graphics chips are often mounted this way, which is why they cannot be repaired with a quick touch of a soldering iron.
Reflow. Heating a chip and its joints so the solder melts and re-forms the connection. It can restore a joint that has cracked from heat and cooling. The result is sometimes temporary, so if a shop proposes reflow, ask what test pointed to the chip and how long the repair is warranted.
Reballing. Removing a chip, cleaning the pads, fitting new solder balls and putting the chip back. It is a heavier job than reflow. We do not carry out reballing of graphics chips. If a shop offers it for a graphics fault, ask for the evidence that the chip is the cause, because heat, drivers and loose connections can look the same.
Power and start-up terms
Charging IC and charging port. The port is where the charger plugs in, and the charging IC controls how power reaches the battery. A worn port is a mechanical fault. A failed charging IC is a board fault, and they are repaired differently. See our guide on charging port repair.
Embedded controller (EC). A small chip that looks after the power button, the keyboard, charging and the fans. When it misbehaves the laptop can refuse to start even though the board is otherwise fine.
BIOS and firmware. The first software the laptop runs. It lives on a chip on the board, and a corrupted BIOS can stop the laptop starting. Fixing it can mean a recovery procedure from the laptop maker or rewriting the chip, and it is a job for a technician, not a random download.
CMOS battery. A small coin cell that keeps the clock and settings alive when the laptop is off. A weak one shows up as a clock that resets and start-up errors. See CMOS battery failure.
POST (power-on self-test). The check the laptop runs when it starts. Beeps, blinking lights or a stuck logo at this stage tell the technician where to look.
Cooling terms
Thermal paste and pads. Paste fills the tiny gaps between a chip and the heatsink so that heat can pass. Pads do the same job on memory and power parts. Both dry out or tear with age, and replacing them is the core of a laptop service. See what thermal paste does.
Heat pipe and heatsink. Copper tubes and metal fins that carry heat from the chip to the fan. Dust between the fins is the usual reason a laptop runs hot.
Thermal throttling. The laptop slows the processor on purpose to stop it overheating. A machine that is quick for ten minutes and then crawls is probably throttling.
Screen terms
Panel. The display itself. Backlight: the light behind it. When the backlight fails the picture can still be there but too faint to see. Display cable: the flat cable, often called eDP, that carries the picture from the board to the panel through the hinge. A cable fault causes flicker or lines, and it is usually cheaper to fix than a panel. Our guide to screen lines and patches shows how to tell them apart.
Body terms
A, B, C and D panels. Technicians name the casing parts by letter. A is the back of the lid, B is the bezel around the screen, C is the keyboard deck and palm rest, and D is the base cover.
Hinge mount. The plastic or metal post inside the lid or the base that the hinge screws into. When it cracks, the hinge goes loose and the casing splits. See hinge repair.
Fabrication. Rebuilding or reinforcing a broken part of the casing, such as a cracked hinge mount or corner, when a new part is not available or costs too much. It is done with adhesives, reinforcing plates or a rebuilt section. Ask for photos of the finished repair. Our pages on body fabrication and laptop body repair near me show what is possible.
Storage and data terms
SSD, NVMe and M.2. An SSD stores your files on memory chips. M.2 is the small slot shape, and most M.2 SSDs use the faster NVMe type, though some use SATA. Not every laptop has a free slot, so check before you buy.
Bad sectors. Areas of a drive that can no longer be read reliably. They are an early warning on a hard disk. See signs a hard drive is failing.
Cloning. Copying a drive exactly, used when moving to a new SSD. It saves reinstalling everything.
What the words mean when a shop says them
| The shop says | It usually means | Ask this |
|---|---|---|
| "The motherboard is dead" | The board is not powering up or not passing a test | Which test, and could a single part be replaced instead? |
| "It needs chip-level work" | A small component on the board has failed | Which component, and what is the warranty on it? |
| "We will reflow it" | Heat is applied to re-form solder joints | What pointed to this chip, and is the fix expected to last? |
| "A new board is needed" | The whole board is swapped | Which grade of board, and what does it cost against a component repair? |
| "It needs fabrication" | A broken piece of casing is rebuilt | Can I see photos of a similar repair, and how long will it take? |

Frequently asked questions
What is the difference between board-level repair and replacing the motherboard?
Board-level repair fixes the failed part on the board. Replacement swaps the whole board. The first costs less when it is possible, and the second is the answer when the damage is too widespread.
Is reflow a permanent fix?
Sometimes, but it can be temporary because the cause of the cracked joint, usually heat, is still there. Ask how the result is warranted.
Does a graphics fault always mean a graphics chip repair?
No. Heat, drivers, display cables and loose connections can all look like a graphics fault, so these are ruled out first. Our graphics card repair page explains what we do and what we do not.
