In thirty-six years of fixing computers, the repairs that go smoothest all have one thing in common. A couple of small things were handled before the machine ever reached my bench. None of it is hard, and doing it can save you time, money, and once in a while something you cannot replace.
Back up your files if the machine still turns on. Photos, documents, anything you would hate to lose. A copy to a USB drive or your cloud account is plenty. Most repairs never touch your files, but "most" is not "all," and a drive that is already failing can go from slow to gone with no warning. If the computer will not boot, do not worry about this part. Just tell me, and tell me which files matter most, so I can make recovering them the first thing I do.
Write down the passwords I will actually need. The big one is the login to Windows itself, whether that is a PIN, a password, or a Microsoft account sign-in. Without it, a lot of the work either slows down or stops at the first screen. If you use a Microsoft or Apple account to sign in, the email and password for that account matter too, because more and more repairs need it to reactivate or reinstall. Bring these written on paper. Do not email them to me.
Write down what is actually wrong, not just that it is wrong. "It is slow" tells me less than "it takes four minutes to open email, and it started last Tuesday." When did it begin, what were you doing, does it happen every time or now and then. If there is an error message, the single most useful thing you can do is take a photo of it with your phone. The exact wording often points straight at the cause.
Bring the charger, and for a laptop, bring only the laptop and its charger unless the trouble is with something else. I do not need your monitor, keyboard, or mouse for most jobs, and leaving them home means fewer things to keep track of. For a desktop, the tower is usually all I need. If the problem is the screen or a port, then bring that piece too so I can see it fail.
Stop using it if you think the drive is dying or files are at risk. I know that is the opposite of your temptation. When a computer is acting up, the instinct is to keep poking at it or run one more cleanup tool. But if the drive is failing, every extra hour it runs is a chance to lose more of what is on it. Powering down and bringing it in is the safer move.
That is the whole list. None of it takes long, and every item on it removes a delay or a risk on my end. Handle what you can, skip what does not apply, and do not let any of it stop you from bringing the machine in. A computer you are worried about is always better sitting on my bench than sitting at home getting worse.
Bring it in, and bring this list with it.
