Laptop slow to a crawl. (1 Viewer)

A little reminder to those using laptops. They are very sensitive to the compacity of the power supply.

For example, I setup a laptop connected to a dock though a USB-c cable that should power and charge the computer and it worked well. A week later the computer was a complete dog with the CPU pegged at 90 to 100% with nothing unusual running. It soon shut down when I disconnected it from the dock; it's battery was dead. It turns out it was drawing the extra power from the battery. When that was drained the computer reduce the processor speed for the lower power available.

Leaving it connected to the mains all the time, does it no good either.

Hmm. Haven't used a PC in 20-ish years but my success with laptops I think is generally that mine don't move.
The extra wear and tear from those who have to be mobile with theirs, shoving it in and out of backpacks, makes a huge difference. Mine rarely travels and I think that has helped it avoid many issues.

Mines sits in a a dedicated dock, i have one at home and one in the office.

When i'm out and about the battery life is still pretty good, but if I do need to work of a mains adapter and charge it, it's a huge 135W thing that isn't vey lightweight to cart about!

I do have a much smaller 90W version that will hold it's charge, but not charge it up whilst using it.

I have what is labelled 'duff battery' that sits in the laptop, when plugged into the mains.
If I need the portability, I swap for a good battery, make sure that is charged in the laptop and replace with duff battery when back home.
It can runn without the battery, but you lose everything if the power goes out.

Worth noting: Some USB-C docks average 45W to 65W output! Modern laptops require much more typically 90-140W when running on full performance and charging. I use a DellWD22B4 with an 180W PSU on my gaming laptop and can connect many things and still charges battery!

If your dock cannot meet the laptop demand it will slowly discharge and because of this your CPU will be throttled and will drop to the lowest clock and will try completing background tasks.

I have the luxury of practically never needing my battery. It's just not a factor for me. Anytime I'm mobile and travelling, I'm OK plugging the thing in, so thankfully don't have to worry about that.

I also have a sort-of dock, well, it's not really - it's one single USB that goes to a hub that ALL my peripherals are connected to, including a INSIGNIA magic-box that provides me with dual monitors even tho my laptop does not support it - truly magical! All I have to do is plug in that single usb and I'm home free as if it were a docking station almost.
