Repair Case Studies

A MacBook Pro that would not turn on

Testing traced a short circuit to the chip supplying power to the storage memory. After the approved board repair, the MacBook powered on again. The technician completed the final checks and confirmed it was ready for collection.

A failed GPU power controller

The Asus would not power up. Diagnosis identified a fault in the GPU power-delivery controller. We ordered a replacement chip with an expected delivery time of up to two weeks.

The customer agreed to a £100 non-refundable attempt fee, with £300 remaining only if the repair succeeded. The quoted total for a successful repair was £400.

After the chip was replaced, the laptop passed several hours of stress testing and was collected in January 2026.

A burnt board trace and a damaged screen

A shorted capacitor and burnt resistor had damaged a copper trace on the motherboard. We replaced the components and rebuilt the trace. The laptop then powered up.

The customer also approved a used 4K touchscreen. The agreed price was £600 for the board repair and display, plus £19 return shipping. The £128 already paid was deducted, leaving £491 to pay.

A burnt resistor on a Surface Pro 4

Testing led to a burnt resistor on the motherboard. Replacing it restored operation. We then re-bonded the display, assembled the tablet and confirmed it was ready for collection.

The customer collected the Surface and paid £200. This was the fault found in this device; a similar power symptom on another Surface does not establish the same diagnosis.

A failed capacitor on an Asus laptop

Replacing a faulty motherboard capacitor restored the laptop to working order. The customer was notified and later collected it.

The customer remarked on the quick completion when collecting it.

An iPhone XS tested through the weekend

We restored power to the phone, then traced the remaining Face ID problem to the proximity-sensor flex assembly and repaired it.

The technician tested the phone through the weekend with a workshop SIM, including normal use. The customer collected it and paid £350.

Missing board components replaced

Around twelve capacitors and resistors were missing from the board. We soldered replacements into the affected positions and confirmed that the phone worked.

The customer collected it and paid £80.

An HP laptop back on after liquid damage

Liquid had reached the motherboard. After we cleaned it and replaced two damaged components, the laptop powered on. Once we had the password for testing, we finished the checks and confirmed it was ready for collection.

A burnt display circuit on a MacBook Pro

Liquid had burnt out the display circuit on the logic board. We bridged the 5 V camera line at the display connector, fitted a new coil and replaced the display controller chip. The screen worked again, and full testing followed.

Five burnt tracks behind a charging port

Five tracks near the charging port had burnt deep into the board, and each attempt to rebuild them shorted again. We opened up the damaged area, separated the tracks and fitted a new charging port. It charges from one side only, the best result this board allowed. When the repaired wires later came loose, we re-soldered them and sealed them with UV-cured mask.

Corroded capacitors on an HP 14

Corrosion had eaten through many of the capacitors on the motherboard. We cleaned the board and replaced all of them. The laptop then worked.

One corroded capacitor, one dead laptop

The CPU power line was damaged. The cause was a single, badly corroded capacitor on the CPU power converter. Replacing it brought the laptop back.

Broken fan-control transistors

The tiny transistors that control the fans had broken legs. We rebuilt the connections, and the fans worked normally again.

A 3.3 V short after liquid damage

Diagnostics found heavy corrosion on the motherboard and a short circuit on the 3.3 V line. We cleaned off the corrosion and repaired the 3.3 V line.

Restoring access to an iPhone XS backup

Touch still did not work after a screen replacement. The customer’s priority was the data. An attempt to control the phone using a mouse adapter did not provide access, so work moved to the logic board.

The technician separated the stacked board and used a donor board during the repair. The phone then worked well enough to create a backup. The customer was informed that the backup was available for transfer to another phone.

The record confirms recovery and a £550 payment. It does not establish that the handset was returned as a lasting everyday repair.

Galaxy S6 data read from its storage chip

Thermal inspection found abnormal heat around the storage area. The technician removed the storage chip and read it using an easyJTAG programmer. The notes confirm that photographs, contacts and video files were recovered.

The customer postponed taking the recovered data. The final note records collection of the handset and a £25 payment, with the recovered data still available at a quoted £750. That quote was not a completed £750 sale.

This was a recovery route for this particular device. It should not be read as a promise that removing a storage chip will recover data from another phone.

No repair, but every file recovered

The screen was cracked and the board had been flooded; the main power controller had burnt through. A repair made no sense. With BitLocker unlocked, we copied the drive and recovered all of its content.

A black screen without a drop

The screen had gone black during normal use. The motherboard checks found no fault, so we quoted for a screen replacement. The customer approved it, we ordered and fitted the screen, and confirmed the MacBook was ready for collection.

A desktop rebuilt with a replacement motherboard

We sourced and fitted a replacement motherboard. The job also included power-supply and cooling work, followed by a fresh Windows installation.

The workshop confirmed that the system worked. Reinstalling Windows was part of this job, not a rule that applies to every motherboard replacement.

Hardware repair followed by a Windows boot fault

After the motherboard swap, the Dell started with a workshop SSD but blue-screened with the customer’s drive. That separated the remaining boot problem from the replacement board.

The agreed £300 package included the motherboard swap, a replacement SSD, an enclosure and Windows installation. The replacement SSD was fitted and Windows reinstalled. The enclosure arrived before collection.

An HP laptop working after corrosion cleaning

We cleaned corrosion from the motherboard. The technician then confirmed normal operation, including the fan.

The customer paid £99 and collected the laptop.

A broken front arm on a DJI Mini 4 Pro

The drone had a broken front-right arm. We ordered the replacement, fitted it and tested the drone.

The customer also tested it on collection. The recorded repair price was £150.

Working after cleaning, then the sound fixed

After a liquid-damage clean the MacBook worked, although the screen kept visible water marks. The audio did not work, so we repaired that too.

A charging port eaten by liquid

Liquid had corroded the charging port. We replaced three resistors on the board and fitted a new port. Everything worked apart from the keyboard; the owner chose to use a wireless keyboard.

Missing components and a new charging port

After liquid damage, a few corroded components had gone from the board completely. We cleaned it, replaced the missing parts and fitted a new charging port. Full testing passed.

Coffee on a VivoBook 17

Coffee had caused a short on the main power line and flooded the hard drive. After ultrasonic cleaning the board worked again. The drive and its data could not be saved, so we fitted an SSD and installed Windows.

A new screen and keyboard base

The top half had survived apart from the screen, but the board in the keyboard base was dead. We fitted a new screen and a replacement keyboard base.

Liquid on the charging-port side

Liquid had reached the charging-port side and burnt components on the board, and the battery had started to swell. We repaired the board, replaced the charging port and fitted a new battery. It was ready the next day.

Liquid damage that reached the charging port

Diagnosis found liquid damage around the USB-C charging port. We cleaned the board and fitted a new charging port.
