A professional computer repair service handles problems that range from a cracked laptop screen to a desktop that will not boot, a MacBook with a swollen battery, or a computer overwhelmed by malware. Unlike phone repair, where the device fits in your palm and the repair takes under an hour, computer repairs often involve larger hardware, more complex diagnostics, and software issues that require patience and deep technical knowledge.
At PC Mobile, our technicians repair laptops from every major manufacturer — Dell, HP, Lenovo, Asus, Acer, and Samsung — alongside Apple MacBooks, iMacs, and custom-built desktop PCs. Whether your computer is running slow, will not turn on, has a cracked screen, or needs a hardware upgrade to keep up with modern demands, we diagnose the problem, explain your options honestly, and fix it right. Every computer repair comes with our 30-day warranty on parts and labor.
MacBook Air, MacBook Pro 13″ and 15″, iMac. Screen, battery, keyboard (butterfly and scissor), logic board, macOS recovery.
Blue screen errors, boot loops, failed Windows updates, corrupted macOS installations, and frozen operating systems are all problems we diagnose and resolve. We repair Windows 10, Windows 11, and macOS software issues without unnecessary factory resets — preserving your data and settings whenever possible. When a clean installation is truly needed, we perform a full backup first.

We handle Apple-specific challenges including Retina display replacement, Apple Silicon diagnostics, T2 security chip issues, and macOS recovery.

We believe every device deserves a second life. The parts inside your repair determine how long that repair actually lasts. A cheap screen might look fine for a week, then start showing yellow tint or losing touch accuracy. A low-quality battery might hold a charge for three months, then start swelling. We only use parts that meet or exceed original manufacturer specifications — and we back every repair with our 30-day warranty.
We use screens that meet or exceed original manufacturer specifications — accurate color reproduction, correct brightness levels and full touch sensitivity from edge to edge.
Our batteries are tested for stable voltage output, correct capacity ratings and thermal safety. We will never install a cell that could swell or overheat in your device.
Getting your phone fixed should not be complicated. Here is exactly what happens when you bring your device to us.
It depends on the repair. Simple fixes like SSD upgrades, RAM expansion, and virus removal are often completed same day. Laptop screen replacements typically take one to two hours. More complex work like data recovery, logic board repair, or ordering specific parts may take one to three business days. We give you an estimated timeline before starting any work.
In many cases, repair is significantly cheaper than replacement. An SSD upgrade and RAM expansion on a three-to-five-year-old laptop can make it feel new for a fraction of the cost of buying a replacement. However, if the motherboard has failed, the repair cost exceeds half the price of a comparable new laptop, or the device no longer receives operating system updates, buying new may be the better choice. We will give you an honest recommendation.
In many cases, yes. Data recovery success depends on the type of failure — logical failures (corrupted file systems, accidental deletion) have high recovery rates. Mechanical failures (clicking sounds, motor failure) are more challenging and sometimes require specialized tools. We assess the drive and give you an honest probability of recovery before starting work.
Yes. We repair both Apple MacBooks (Air, Pro, iMac) and Windows laptops from Dell, HP, Lenovo, Asus, Acer, Samsung, MSI, and all other major manufacturers. Our technicians are experienced with both macOS and Windows operating systems.
In most cases, yes. Replacing a traditional hard drive with an SSD and adding RAM are the two most effective upgrades for improving speed. Not all laptops support upgrades — some ultra-thin models have soldered RAM or storage that cannot be replaced. We check your specific model and tell you what upgrades are possible before proceeding.
Yes. We remove viruses, spyware, adware, ransomware, and other malicious software using professional-grade scanning and removal tools. We then clean up any system modifications the malware made and help you set up basic protection against future infections.
Yes. Laptop overheating is usually caused by clogged air vents, dried thermal paste, or a failing fan. Our thermal service includes full internal cleaning, thermal paste replacement, fan inspection and replacement if needed, and airflow testing. This service often extends a laptop’s usable life by years.
