Regarding power management
Honestly, when it comes to repairing or running an old laptop or desktop PC, power management isn’t really a priority for me. Sure, it’s something to consider, but we’ll never be able to create or fix existing energy consumption. At best, we can try to reduce it, aye… But that usually comes at the cost of performance. And let’s be honest, most of these older machines already use very little energy compared to modern systems. Except in rare extreme cases.
BENCHMARK (PassMark & Geekbench)
I’ve done Passmark tests on machines I have in stock, as well as during repairs or Linux/Windows replacements for clients, both inside and outside the Repair Café context. That list is far from complete or fully accurate though, since it only reflects an upper average. Some older PCs, even with the exact same system setup, are clearly at the end of their life with benchmark scores sometimes up to 80% lower.
Problem
Building a truly reliable system benchmark would require installing each distro cleanly on every system, formatting, testing, and repeating that process for every variation. That’s clearly not realistic. So the best we can do is rely on benchmarks from the developers themselves and community recommendations. After then, compare those to the actual hardware we have in front of us. At a Repair Café, we rarely have more than 20 minutes to check, test, and diagnose a computer.
Diag
For me, there are key points that need to be checked in order, with some optional. But still important steps. Are we aiming to repair, boost, or completely revive the targeted PC?
- Test the battery and power supply (using a power tester or plug-in voltmeter to analyze electrical fluctuations → 5 minutes is enough).
- Check the BIOS: update if needed (critical for older PC and hard to find the right files), inspect the hardware, and note down component details.
- See if any spare RAM sticks are available, and check if the PC can be upgraded.
- Check if the HDD is 5400 or 7200 RPM and ask the user if they’d consider replacing it with an SSD or if they’d consider doing so later if the system remains slow and barely usable.
- Boot into Hiren’s BootCD or UBCD, and run MemTest + HDD diagnostics (check if results show GOOD, OK, or TOP and anything below GOOD should trigger a proposal to replace or stop there).
- Compare the hardware with other machines running similar systems and check specific benchmarks. The average is rarely useful in this kind of context.
- Choose and install a suitable distro (try first, because it doesn’t always go as planned).
- Test and time performance: boot time, browser launch, opening a webpage, YouTube playback (480p / 720p / 1080p / higher), LibreOffice or Google Docs link loading, etc.
- Document the process step-by-step in a file (Excel line-per-task or timeline format with headers for each stage).
- Share your experience with others if possible.
Conclusion
That’s what I believe is concrete and actionable. Either we complete an existing file to centralize all this, or we make it available in a readable format for others to access easily.
In any case, it’s clear that we’re all full of good will and ideas. I feel it’s time we centralize everything and stop just talking about it. Its time to act clearly and directly. Starting now.
We’ll move forward more easily and avoid asking ourselves the same 1,500 questions every time.
Anything missing can be added gradually as feedback comes in.
I’ve already shared some tools and links to access online resources and utilities, but I haven’t received any feedback so far.
Am I wrong to be moving too fast? Or do you feel unsure or hesitant about what’s being proposed?
If you have any thoughts, ideas, or suggestions, I’d be glad to hear them.
I’m really looking forward to your feedback.
