People entering the field of computer mend need to do quite a bit of study to find all the tools they need to be able to fix the long list of problems that computers and laptops face. When I first started, I used to carry a huge toolkit full of all sorts of devices. The bag itself looked pretty impressive and had roughly whatever you might ever need. But as time went on, I discovered that 99% of the issues you need to conclude can be taken care of with just a basic set of technical equipment.
If you are going to achieve laptop mend as well as desktop services, I suggest carrying a precision screwdriver tool kit. They cost somewhere around .00 and they are by far the most beneficial item I carry. Laptops and Macbooks especially tend to use really small screws to hold components together. Small torx screws are pretty much an entry barricade for new technicians who don't have the touch to know that they even needed a small torx screwdriver.

The second best tool for computer mend is a Usb stick. You can store every single program you will ever need to troubleshoot a computer problem on one microscopic stick. I store multiple types of anti-virus programs, anti-malware programs, rkill utilities, Hijackthis installations, favorite browser install kits, data back up software, data change software and salvage programs. On top of storing your mend software, you can also use the Usb key to change drivers and other files that you often need to download on-site.
While the Usb stick and the precision screwdrivers will get your through 90% of your problems, you will need a very diverse kit for the remaining problems. You'll need to get a Cd pouch full of operating law disks and manufacturer salvage disks. Don't forget that you'll need one of each kind for both 32bit and 64 bit operating systems. Then, you'll also need to carry a power supply tester for computer repair. On the laptop mend side, you will need to spend in a voltmeter to troubleshoot inverter problems and dc power jack issues.
Finally, the last additions to your toolkit will be thorough technician items. Flashlights, measuring tape, thermal paste, electrical tape, extra screws and more... Most of these tools will rarely be used. But when you need them, you'll really wish you had them. As you get more comfortable doing computer repair, you'll be able to practice tailor your kit to your personal preferences. With sufficient experience, you might conclude to add soldering iron and a heat gun for more advanced board level repairs.
