This is why my next laptop will be a MNT Reform, you can change the individual cells yourself: https://www.crowdsupply.com/mnt/reform

I just received my developer beta MNT Reform, and I've been really enjoying it. They keyboard takes a bit of getting used to, but everything's very cute.

Any chance you could host a 'sosreport' so I could get a look at the hardware config ?

It really speaks to how badly innovation has slowed in chip design that a 10+ year old budget laptop is still comptitive hardware

It's really not. The top CPUs in T420s are power hungry 35W parts that are far slower than current https://hwbot.org/submission/4201949_toanmai84_xtu_core_i7_2... https://www.hwbot.org/submission/4330573_tankdriver69_xtu_co...

That is a different problem. I've also been able to buy non-knock off batteries for just about all electronics up to a few years ago when companies decided that soldered in batteries shorten the time-to-landfill of their products improving their revenues. Seriously: there is no reason why there could not be a standard form factor for battery cells. If we can do hard drives, CPUs and RAM I'm sure we can do batteries t…

You're still talking past me. A standard form factor won't solve the trust problem. Most people don't know how to choose a proper hard drive compatible with their M.2 adapter or cable for their USB device. Many people also buy counterfeit USB sticks and SSDs that don't have near the capacity they advertise. You and other tech-literate people aren't the only consumers manufacturers are selling to. Nor are people alway…

The trust problem is better solved by relevant legislation. The counterfeit problem is better solved by relevant legislation. Intentional incompatibility with generic replacement parts will eventually also be solved by, you guessed it, relevant legislation.

I can unfortunately not live with the crap display (I do image editing). What's the hassle like?

Pretty easy, but a bit expensive considering the laptop itself only costs around $150. A 1080p display + adaptor board for it costs about $100 and the 1440p display + adaptor is around $150. If you look up "T420 ips mod" you'll find lots of pictures and tutorials.

Thanks!

I just use another monitor, while the laptop display act like a second display.

Need it on the road.
