How to Choose a Computer Repair Service in Dhaka Without Getting Ripped Off
11 June 2026 · 6 min read · BAYAS Editorial
Every week at BAYAS, we receive 5 to 10 devices that were "repaired" elsewhere and came back worse. A MacBook with a counterfeit battery that swelled within two months. A Dell laptop with a "new" screen that had dead pixels on day three. A desktop whose "repair" was just a Windows reinstall — the failing power supply was never touched.
Choosing a computer repair service in Dhaka is not just about price. It is about whether your device comes back healthier or sicker.
This guide explains the seven checks BAYAS technicians recommend you make before handing your device to anyone — drawn from eight years of servicing laptops, desktops, and MacBooks across 36 Dhaka zones.
1. Ask whether the technician diagnoses in front of you
A legitimate repair begins with diagnosis, not guessing. If a shop takes your device to a back room and returns 30 minutes later with a quote, you have no way to know what they actually found — or whether they created a problem to charge you for a fix.
What to expect: The technician should power on the device in front of you, run visible tests (voltage, POST, storage SMART, thermal), and explain what each test reveals. At BAYAS, we perform structured diagnostics at your home or office — you see every step.
Red flag: "We need to keep it overnight for testing" when the fault is basic (no power, no display, slow boot). Basic diagnosis takes 10 to 30 minutes with proper tools.
2. Verify they use genuine or grade-A parts
The Dhaka laptop spare parts market is flooded with counterfeit components. A "genuine HP battery" sold at BDT 1,800 is almost certainly fake — genuine batteries from authorized distributors cost BDT 3,500 and up.
| Part | Genuine price (Dhaka retail) | Counterfeit price | Risk | |---|---|---|---| | Laptop battery | BDT 3,500 – 12,000 | BDT 1,200 – 2,500 | Swells, shorts, fire hazard | | Laptop screen (15.6" FHD) | BDT 5,000 – 9,000 | BDT 2,500 – 4,000 | Dead pixels, dim backlight, fails in months | | MacBook battery | BDT 7,000 – 18,000 | BDT 3,000 – 5,000 | Warps trackpad, cracks chassis | | Laptop charger | BDT 2,500 – 5,000 | BDT 800 – 1,500 | Voltage spikes, fries motherboard |
What to expect: The service should provide a retail invoice in your name from an authorized Dhaka retailer (StarTech, Ryans, Global Brand, Computer Mania). If they refuse to show the receipt, assume the part is not genuine.
BAYAS practice: Every replacement part comes with the original retailer invoice. You see the exact price we paid. No markup, no hidden margin.
3. Check the warranty — in writing
A verbal "we guarantee our work" is worth nothing. A written warranty with specific terms is the difference between a responsible service and one that disappears after payment.
What to expect at minimum:
- Workmanship warranty: 30 days minimum (BAYAS provides this on every job)
- Parts warranty: Manufacturer or retailer warranty, typically 3 to 12 months
- Written terms: what is covered, what voids it, and how to claim
Red flag: "Warranty void if you open the device" — this prevents you from getting a second opinion. A confident technician stands behind their work.
4. Demand a price breakdown before work begins
The most common complaint we hear: "They quoted BDT 2,000 on the phone, then charged BDT 8,000 after opening."
What a proper quote includes:
- Diagnostic fee (if any)
- Parts cost with part number and source
- Labor charge (capped, not hourly)
- Total, with tax if applicable
- Timeline
BAYAS practice: Every quote is shared on WhatsApp before work begins. Diagnostic fee is credited toward repair if you proceed. Labor is capped per job type — never per hour, never open-ended. Parts are billed at retail invoice cost.
5. Look for technicians on payroll, not freelancers
Many "repair services" in Dhaka are WhatsApp groups where the admin forwards your job to whichever freelancer is available. There is no quality control, no accountability, and no recourse if the freelancer damages your device.
What to check:
- Does the service have a physical address? (BAYAS: Akota Society Bhavan, House 216, East Chanpara, Uttarkhan)
- Are technicians full-time or gig workers?
- Is there an office phone number you can call?
- Does the service have a website with real content (not just a Facebook page)?
A physical workshop with full-time technicians signals investment in reputation. Freelancers can change their WhatsApp number in 30 seconds.
6. Ask about chip-level capability
Most repair services in Dhaka are "board-swappers" — they replace entire assemblies rather than repairing at component level. A dead motherboard? They quote for a new one. A flickering screen? They swap the whole display assembly instead of checking the LVDS cable.
What chip-level repair means:
- Replacing individual power ICs, capacitors, and MOSFETs on a motherboard
- BGA rework: removing and reattaching chips using hot-air stations
- Ultrasonic cleaning for water-damaged logic boards
- Boardview-based diagnostics: tracing circuits using schematic files
Why it matters: A chip-level repair for a power IC costs BDT 3,000 to 6,000. A board swap costs BDT 15,000 to 35,000. The difference is not skill — it is equipment and training. BAYAS invested in microscopes, hot-air rework stations, and programmable power supplies so we can fix boards, not just replace them.
7. Check for transparency signals
Before you book, browse the service's website and online presence:
| Signal | Good | Bad | |---|---|---| | Physical address | Full address visible | No address, only WhatsApp | | Pricing | Ranges and examples published | "Call for price" only | | Phone number | Visible, real number | Hidden or fake | | Reviews | Google reviews, real names | Only screenshots, no links | | Website content | Original, detailed, helpful | Thin, copied, generic | | Photos | Real workshop, real technicians | Stock photos, no faces |
A service that is transparent before you pay will be transparent after you pay. Opacity before payment is a reliable predictor of opacity after.
What to do now
