- Average Profit for each Laptop Repair is about $100. Most take less than an hour once you’ve mastered the Laptop Course. One person can easily do 2-3 of these per day while still working on other things.
- From repairs alone, it’s easy for a one-man operation to be producing a $1500 per week income. That averages out at just under $80,000 per year.
- With refurbishment, we’ll teach you how to sell broken laptops at 100% more than the price you paid. You’ll make an average profit of $120 on each laptop you refurb. Higher, once you use our methods for sourcing parts cheaply.
- From refurbishment, working solo you can expect to do 2-3 a day, this will allow you to make a profit from $62,000 – $100,000 every year!
- The Laptop Course teaches you to easily scale up your refurb business, and once you start doing that and training employees with this course, the sky is the limit. The market for 2nd hand laptops is at the beginning of a huge growth curve, your potential profits are only limited by the size of your ambition.
- Once you combine the 2 Business Models we teach you, a six-figure income isn’t a dream, it’s an expected reality.
- Question:
- Would love to know how you diagnose motherboards on a component level. What tools do you use?
- Answer:
- I find it is very hard to explain this. actually, it is very simple and can be described in two words: current and singal. read the current change during booting tells you where the machine stopped. check the singals on the different part of motherboard tells what is wrong or what may missing.
- Tools are: smd rework station, bga rework station, power supply has current meter. all the rest tools you can find in any radio tv repair shop.of course all the datasheets for the components, especially the schematic diagram, you will find it much difficult without it.
- What are common faults on mainboards?
- Do certain components fail? Is there a trend as to which parts fail quite often?
- Different maker/model has different common fault. Toshiba S1 is vga chip, and can’t be repaired(well, almost can’t be repaired because the pcb quality is not very good so successful rate is very low).
- HP DV2000, 6000, 9000, compaq v3000, v6000, dell 1210, all those use nvidia chips have problem on vga chip or north bridge. easy to repair but have to make fan keep spinning after repaired, otherwise will break down in 1 or 2 week again.
- hp nx5000, cpu pwm chip dry joint. acer 290, cpu pwm dry joint.
- hp dv1000, compaq m2000 protection circuit easy to blow up.
- ibm t40 vga dry joint problem.
- These are just few of them. every machine has its own common fault. but dry joint is the common problem for all machines. Motherboard repair is not as difficult as people thought, i think much easer than repair a tv.
- Question:
- How i fix a DV6 with power problem. The problem of machine is it cannot power up at all.
- Answer:
- Doing routine check:
- 1. system power: 3V, 5V all presented – ok
- 2. NBSWON signal: 3.3V presented – ok
- 3. press power button, NBSWON pull down to 0V, ok
- 4. check DNBSWON while press power button, no response. – problem.
- in here I made a mistake, I didn’t pay attention of the voltage of DNBSWON, this mistake waste me the next few days time. It should be 3.3V, but only about 1V.
- Change EC as usual, because I thought the EC has problem. Then the big trouble comes – it auto power up once I plug in the power but stop in 0.04A current. Check and find no S5_ON signal, which indicate south bridge has problem, so change south bridge. But still same problem and still no S5_ON. I find that the EC I change is kb3926A rather than kb3926C. In most case, this is no problem but in very rare occation…
- So I find a 3926C and put on. Now the motherboard is back to the same problem while I first start to check! So I change a wrong EC and this time I change a correct one, and also EC has no problem!
- Because EC will start to read bios once the power plug in(not as people think, once you press power button). I check BIOS chip, BIOS_CS should have a countinue wave form but it just one stright line. BIOS chip is faulty, I replace the BIOS chip and it works perfect.
- Question:
- Dell 1525 Inspiron that says system does not recognize the installed battery this system will not charge the battery.
- Answer:
- Charging battery in Dell laptop involves two major chips: EC(or someone call it super IO), PWM chip for battery charging. BIOS has no part of charging. Battery communicate with EC through SMB(system management bus??) and EC controls charging PWM. Fix charging problem is very hard in laptop repair, you must fully understand schematics, where all the signals come from and where to go.
- Today’s laptops are less and less with programmed EC, Dell 1525 has no programmed EC so it can be replaced with same model.

- We strive to be the number one institute offering the most competitive Laptop courses which cover the entire essential areas varying from its hardware to software parts. Hence, after completing the course you will be able to fix any laptop problem.
- Niche Skill – Right now, the skills taught by the Laptop Course aren’t widely known, in 5 years they’ll be as commonly known as PC Repair. So now is the time to establish a dominance of your local/national market before the competition discovers it.
- Scarcity = Higher Profit – Given the fact that this is currently a niche skill, you can earn double the wage of someone who does more common tech repair. But to enjoy this over-valuation, you have to take advantage of it now!
- Prices Rising – A few years ago, people thought it ridiculous to spend more than a couple hundred dollars on a Laptop. Now, new models are coming out at $2000 and this will only increase. This means two things for our students: 1. People will spend more on repairing their Laptops. 2. People will spend a lot more on refurbished Laptops. This means the potential customer base will boom in the next couple of years.
- Laptops Being Kept For Longer – Given the higher price tags and better build qualities of today’s Laptops, people are no longer regarding Laptops as temporary commodities.
