c/computer-technicians

My neighbor, a retired mechanic, said 'You fix computers like I fixed cars. You're just swapping parts until it works.' That stuck with me.

I just read that over 40% of consumer PC repairs in 2023 were for liquid damage, mostly from spilled drinks.

Saw this stat in a trade magazine summary. It made me realize how many of my own calls are for sticky keyboards and fried motherboards from coffee or soda. I've started keeping a big bottle of isopropyl and a ton of Q-tips in my kit as standard. What's your go-to method for dealing with a fresh spill before the customer brings it in?

Showerthought: I keep seeing techs skip the basic voltage check on power supplies

Had a client bring in a gaming rig from a shop in Austin that said the whole board was dead, but their meter showed 0.0V on the 12V rail before they even started. How many times have you seen a simple power check get missed, leading to a wrong diagnosis?

A client's gaming rig in Phoenix had a weird power cycle issue that took me three visits to figure out

It would boot for 30 seconds then cut off, but only when the room was warm. Turned out the thermal paste on the CPU was completely dried and cracked, causing an instant overheat. Has anyone else seen a failure that quick from old paste?

TIL about a weird fix for a laptop that wouldn't charge past 80%

Had a client's Dell laptop that would just stop charging at 80% no matter what. The choice was between replacing the whole battery or trying a firmware update from Dell's support site that I'd never heard of before. I went with the firmware update, which took about 15 minutes, and it actually worked perfectly. Has anyone else run into this kind of weird battery limit issue with other brands?

Found an old invoice from 2002 and the numbers are wild

I was cleaning out my old filing cabinet and found a service invoice from my first shop job. We charged a flat $45 for a full Windows XP reinstall, which included data backup and all drivers. The real shocker was the hardware note: a 40GB IDE hard drive cost the customer $120. I looked it up, and that's about $200 in today's money. For 40 gigs. Now you get a 1TB SSD for less than that. It just hit me how much the value of storage and our basic labor has flipped. Back then, the drive was the big ticket item. Now, the drive is cheap, but the hour of skilled labor to install it is worth more. Makes you think about how we price things now. Anyone else have old paperwork that shows how much the game has changed?

Remember when we had to explain what a hard drive was to customers?

Back in 2008, a man brought his desktop into my shop in Omaha and asked if I could 'empty the cup' inside his computer because it was full. He had heard about memory and thought it was a physical container. I showed him the actual hard drive, opened his My Documents folder, and we deleted about 2,000 duplicate vacation photos together. Do you ever miss those simple, hands-on teaching moments with clients?

My bench time on laptop motherboard swaps dropped by 40 minutes after I started using a magnetic project tray

I used to spend over an hour just keeping track of all the tiny screws and brackets. Now I use a $12 magnetic tray from Harbor Freight to hold everything in order during disassembly. Has anyone found a better system for keeping parts organized during a full teardown?

Had a client's PC with a weird boot loop, swapped the PSU and it was fixed in 20 minutes

This older desktop in our shop was stuck restarting right after the BIOS screen. I spent an hour checking RAM, the drive, and even re-seating the CPU. Then I swapped in a spare Corsair CX550 from our bench, and it booted straight to Windows. The old PSU tested fine on a basic tester, but under load it must have been failing. Has anyone else had a PSU pass a simple test but still cause a boot loop?

Read that 40% of data loss in small shops is from simple power surges, not drives failing

I was looking at a report from a power supply maker's site, and it said that number. I always thought drives just wore out on their own. How many of you actually use surge protectors on every single workstation you set up?

The difference in my shop after we started using a proper ticketing system

Two years ago, we were still using a shared Google Doc and sticky notes to track repairs, which was a mess. We switched to RepairShopr in 2023 and the change is insane. We went from losing about 10% of our small jobs to forgetting to invoice, to having everything logged and billed. What other systems are you guys using that don't cost a fortune?

Why does nobody talk about the thermal paste application mess I keep seeing on customer PCs?

I've opened up 4 different computers this week from other shops, and every single one had way too much paste squeezed out all over the CPU socket, which is a huge risk for short circuits and a pain to clean up properly.

I switched from using canned air to a small compressor for cleaning PCs

I know everyone says canned air is safer, but after my third can froze up in a row last winter, I bought a cheap 2-gallon compressor with a moisture trap. It has way more power for clearing dust from heatsinks and costs nothing to refill. Has anyone else made this switch and found a good low-PSI nozzle for it?

PSA: A $5 can of air fixed a weird server fan noise after three hours of checking logs

Had a rack server making a high pitched whine, not a full failure. Checked all the system logs, temps were fine. On a hunch, I blasted the tiny vents on the fan housing with compressed air. A clump of dust shot out. Noise stopped right away. Anyone else find weird fixes for phantom noises?

Remember when you had to buy a whole new motherboard for a bad capacitor? I just spent $2 on a soldering iron tip to fix one.

Back in the day, a blown cap on a board was basically a death sentence for the whole system. Now I keep a cheap iron and a bag of caps on the bench. Fixed a customer's old gaming rig last week that just needed a single 1000uF cap swapped. Took 5 minutes. What's the oldest piece of gear you've brought back from the dead with a simple component fix?

Had a client in Dallas bring in a laptop that wouldn't boot, and their comment about the fix stuck with me.

It was a Dell Latitude with a failed CMOS battery, a simple $5 part. I swapped it out and it booted right up. When I told them the fix, they just looked at the old battery and said, 'So the whole thing was held up by a watch battery?' It made me realize how many problems come down to one tiny, cheap part. Anyone else have a story about a simple fix that surprised a customer?

This weird power supply issue took me a full day to figure out

I had a computer that would boot for about ten seconds, then shut off. No beeps, no post, nothing. I swapped the RAM, the CPU, even the motherboard, thinking it was a short. I must have spent six hours on that. The whole time, the power supply tested fine with my basic PSU tester. Turns out, it was a specific voltage rail on the PSU that would drop under load, but only after it warmed up a bit. My tester just showed a pass because it wasn't drawing enough power. I finally found it by swapping in a known good unit as a last resort. I felt like an idiot for not trying that first, but everyone always says to test the PSU first, right? Has anyone else run into a PSU that passes a basic test but fails under real load?

I thought those $15 anti-static mats were just a gimmick until a motherboard fried on my bench

I was working on a custom build for a client in Tampa, and I figured my usual routine of touching the case was good enough. After I zapped a perfectly good board (which cost me $200 out of pocket, by the way), I finally caved and bought one. Has anyone else had a specific part die on them that finally made you take static seriously?

I bought a $150 'diagnostic' tool that was basically just a fancy USB stick

Saw it advertised online last month, claimed it could run deep hardware checks on any laptop. It literally just ran the same free Windows memory test you can download. Took me about 4 hours of messing with it before I realized it was useless. I could have just used a free tool and saved the cash. Honestly felt like a scam. Anyone know a real, reliable hardware diag tool that's actually worth the money?

Had a weird one with a server that kept dropping its RAID array every Tuesday

It was a Dell PowerEdge at a small law firm here in town. For three weeks straight, the array would fail around 2 PM, then come back after a reboot. I finally sat there with a monitoring tool and saw the office cleaning crew plug their floor buffer into the same circuit, causing a tiny voltage dip. Moved the server to a dedicated line and it's been solid for a month now. Anyone else run into a problem that was totally not the computer's fault?

Finally got my bench setup to where I can swap a motherboard in under 20 minutes

I used to have all my drivers in a big plastic bin, but after a job in Phoenix last month where I spent 45 minutes just looking for a specific Torx bit, I bought a $40 magnetic rail system and now everything is right in front of me, so what's the one small change that's saved you the most time on a standard repair?

PSA: The 'free air' can trick for cleaning a laptop fan is a bad idea.

Used a can of compressed air on a dusty ThinkPad T480 fan without holding the blades. Spun it way too fast and now the bearing makes a grinding noise. Anyone know a reliable source for a direct replacement fan, or is this a full heatsink assembly job now?

Question about a client who refused to let me clean their computer

I had a regular customer in my shop last month who brought in a desktop that was running super slow. When I opened it up, the dust was so thick you could write your name in it. I told them I needed to clean it out for $40, but they said, 'No, just make it fast, the dust keeps it warm.' I tried to explain how heat kills parts, but they wouldn't listen. Has anyone else had a client argue against basic maintenance like that?

Rant: I used to spend hours on one machine, now I just swap parts

Back when I started at a shop in Austin, my whole process was about deep diagnosis. I'd spend a whole afternoon with a multimeter, hunting for a bad capacitor on a motherboard or a short on a power rail. It felt like real detective work. About three years ago, the math just stopped adding up. A client with a five year old laptop came in with a no-power issue. I quoted two hours of labor at $85 an hour to find the fault, plus the part cost. They could buy a decent refurb for less. Now, my first move is almost always a known-good swap. Got a weird boot loop? Swap the RAM first. No display? Try a different screen. If the swap fixes it, I order the part. If not, I move on. It's faster for the client and keeps my bench clear. I miss the puzzle sometimes, but the job changed. Has anyone else shifted to this swap-first method to keep up?

Unpopular opinion: I started keeping a $5 USB fan in my toolkit after a server room in Omaha hit 90 degrees last month.
