Dell laptop diagnostics in Warsaw — not sure what’s wrong? Our free inspection takes 5–15 minutes and we carry it out whether or not you decide to go ahead with the repair. Extended diagnostics is free if we perform the repair.
In short: At our Warsaw service centre, we distinguish between two things. Free inspection takes 5–15 minutes, is always free of charge, and lets us determine what’s wrong with your Dell. Extended diagnostics means full disassembly and motherboard measurements — takes 1–3 working days and is free if we carry out the repair. You only pay if you decide not to proceed with the repair.
Our experience — Dell laptop diagnostics
At our service centre in Warsaw, we’ve carried out 27 diagnostics on Dell laptops — it’s the brand that comes to us most often with unclear faults. In total, we’ve serviced nearly 200 Dell laptops, mainly from the Inspiron, Latitude, XPS and Vostro series.
Free inspection vs extended diagnostics — not the same thing
Most repair shops call what is really just a basic inspection 'diagnostics’. We distinguish between these two services to avoid any misunderstanding about the price and scope of work.
Free inspection
5–15 minutes. Always free. We connect the laptop to a lab power supply, measure current draw, and determine the preliminary cause. Free regardless of whether you decide to proceed with the repair.
Rozszerzona diagnostyka
1–3 working days. Full disassembly, voltage measurements on the motherboard, circuit testing according to service schematics. Free if we carry out the repair. Charged only if you decide not to proceed.
After the free inspection, the technician will always tell you straight away whether the problem is obvious or whether extended diagnostics are needed. We always give you the price for extended diagnostics before we carry it out, and it’s fixed — even if during the process we need to order an integrated circuit that costs more than the diagnostics itself.
When you’re looking for laptop diagnostics
You’re here because you’re looking for answers to questions like: laptop won’t turn on what to do, what’s broken in my laptop, how much does laptop inspection cost or free laptop diagnostics Warsaw. It’s all the same situation — we need to identify the cause before we can fix anything.
How the free inspection works step by step
The scope of the inspection depends on what you bring in. The most common case is a laptop that won’t turn on. Here’s how we proceed:
- We connect a laboratory power supply — nearly all laptops run on 19 V. We check whether the laptop draws any voltage at all.
- We measure current draw — this is the most important diagnostic parameter.
- We press the power button and observe the changes — the way current draw rises and jumps tells us whether the laptop is going through initialisation.
- We compare the result with our database — based on the model and current draw, we estimate the cost and time for repair.
What current draw reveals — and why it tells us so much
The laptop’s behaviour after connecting the laboratory power supply already allows us to narrow down the cause at this stage:
- The laptop draws no current at all — likely a break in the power line, damaged input transistors, a faulty charging port, or a frozen BIOS.
- It draws maximum current, the short circuit indicator lights up — we disconnect immediately. This means a short circuit on the motherboard in one hundred per cent of cases, usually on a high-current line. We then disassemble the laptop and locate the short.
- It draws steady, low current — e.g. 0.3 A — and doesn’t respond to the power button — this is usually a more serious problem: the KBC circuit (EC microcontroller responsible for the keyboard and power-on, among other things), the processor, or the graphics card.
- Current draw jumps when the button is pressed — 0.3 A, 0.5, 1 A, 1.5 A — that’s a good sign, the laptop is going through initialisation.
- Current draw stops at one point — e.g. it gets stuck at 0.6 A. Most likely the BIOS has frozen. A full disassembly and EC controller reset often helps.
Our advantage: a knowledge base instead of a technician’s memory
What sets us apart is that we record every repair in our own integrated knowledge base. In most repair services, experience relies on what the technician remembers — and when they change jobs, all that experience leaves with them. With us, all technicians who have worked, are working, and will work maintain a complete technical knowledge base.

In practice, it works like this: we have a large number of jobs, so we have statistics on what most commonly fails in specific models. Thanks to this — knowing the Dell model and seeing how much current it draws — we can estimate the cost and time for repair quite precisely during the free inspection. This is the effect of large numbers: the more cases we’ve accumulated, the more accurate the initial assessment.
We also collect service schematics for popular models in our knowledge base. Our technicians can read them — some have higher education, including graduates of the Military University of Technology in electronics and telecommunications.
Extended diagnostics — what exactly we check
When the cause isn’t obvious, we disassemble the laptop and measure voltages on the motherboard. The starting point is always the same:
- Base voltages 3.3 V and 5 V — these must be present on the board when power is connected. The BIOS and EC controller run on these voltages. If they’re missing, the laptop physically cannot start.
- Voltages on inductors — we check them according to the service schematic, comparing with the values specified for a given power state of the board.
- Tracing breaks — if, for example, 5 V is missing, we trace the line to the power supply circuit and check what’s blocking it.
- BIOS verification — we have BIOS programmers, so we can desolder the memory chip and reprogram it.
- Individual component level — we can pinpoint a specific shorted capacitor or damaged component on the board.
Our diagnostics work like an X-ray. We can break a laptop down to its basic elements and check everything to know with absolute certainty what exactly is damaged. With laptops, most of the time goes into determining what’s broken — the actual repair is simpler, because we know which chip to replace.

That’s why with extended diagnostics we very often repair the laptop almost incidentally — once we know which component to replace, the device is practically fixed.
How much diagnostics costs
- Free inspection — always free, regardless of whether you leave the laptop at the service centre.
- Extended diagnostics with repair — free, included in the service.
- Extended diagnostics without repair — charged according to the price list. We always quote the price before starting work.
- The price of extended diagnostics is fixed, even if we order more expensive parts during the process to verify the fault.

Frequently asked questions
Is Dell laptop diagnostics free?
Free inspection — yes, always and without obligation. Extended diagnostics is free if we carry out the repair; it’s only charged if you decide not to proceed with the repair.
How long does diagnostics take?
The free inspection takes 5–15 minutes — you can wait. Extended diagnostics usually takes 1–3 working days, as it requires complete disassembly and measurements on the motherboard.
Do I have to leave my laptop?
Not for the free inspection — it takes about fifteen minutes. The laptop only stays at the service centre if extended diagnostics is needed.
How do you know how much the repair will cost before you take the laptop apart?
From our knowledge base. We record every repair, so we have statistics on typical faults in specific models. Knowing the Dell model and power draw, we can give a preliminary estimate of cost and time during the free inspection.
Do you also repair motherboards after diagnostics?
Yes. We have microscopes, a soldering station and BIOS programmers, as well as service schematics for popular models. We can identify and replace the specific faulty component on the motherboard.
Prices for all services can be found in our price list.
