Excellent: Tech startup builds repairable, upgradeable notebook computer

Good for consumers and the environment:

Laptops these days are slimmer, sleeker, and lighter than ever—but their repairability and configurability are taking enormous hits in the process. Framework is seeking to roll back the clock in a good way with its first product, the upcoming Framework 13.5-inch laptop.

Following the lead of companies like Fairphone, the startup is focused on respecting users’ right to repair by building systems focused on modular design, with components that are easily configured, replaced, and even upgraded.

Meanwhile, my old Apple Macbook Pro has batteries glued inside and which take 2-3 hours of labor to replace… not repairable, re-usable, recyclable technology.

Texas semiconductor factories shut down during power outage

Semiconductor plants – perhaps five of them – were ordered shut down, in Texas, due to the state’s failed electricity grid.

Semiconductors are manufactured in a chemical engineering process that can take weeks, per chip, along the line. The time required depends on the components being manufactured and can range from weeks to two months.

Thus, shutting down these lines could disrupt service for some time.

There is already a global electronic components shortage that has caused most all major auto manufacturers to temporarily close or slow down auto manufacturing. This shortage is compounded by a multi-day fire at AKM Semiconductor in Japan, last fall. That firm made up to 90% of the world’s components for consumer electronics, plus Bluetooth chips and other items and was expected to cause at least six month delays in parts shipments.

I an electronic item I ordered last October has been postponed indefinitely – a key part was made by AKM. Another item I ordered in January, with expected shipment of Feb 12, was delayed until June 21, 2021.

Can the liquid in your CPU liquid cooler freeze?

The title is a serious question. I have a computer located in the loft of an outdoor shop. The shop and loft are unheated and during the winter, the temperature can easily fall below freezing in the loft.

What happens to the liquid in the liquid cooling system for the CPU when the temperature is below freezing?

It turns out “it depends”: some liquid coolers use water, others use various additives including an anti-freeze material. The only way to know for sure is to contact the cooler manufacturer.

My CPU cooler is an Enermax Aquafusion 240. I contacted their tech support center, who did not immediately know the answer but graciously forwarded the question to their headquarters who got back to me and let me know that they had tested it in the lab down to -15 degrees C (or about +5 deg F).

That’s good information to know! And a big thank you to Enermax for pursuing an answer to that question!
