The #powersupply seems dead. I have other two, so I tried them. One was dead (as written, in italian, on the label), and one turned on the computer but no "bong" from the speaker. And the fan seemed a little more noisy than I remembered, so I checked the voltages and... holy cow 20v! I immediately disconnected it, hope not to have caused further damage. There was no #magicsmoke, only some fishy smell typical of the #capacitors #electrolyte. Not surprising, considered they have leaked.

Solid state batteries theguardian.com/environment/20

Removing the liquid #electrolyte makes batteries less susceptible to fires & Solid-state batteries can be fully charged more quickly… solid electrolytes are less dense, so a solid-state battery can be smaller and lighter & make electric cars smaller and lighter, give them a greater range for the same size and weight…even make electric aircraft a viable proposition.

In the absence of effective electrolyte additives, PET can #depolymerize into its monomer dimethyl terephthalate, which is an unwanted #redox shuttle that induces substantial self-discharge in a lithium-ion cell. This study presents a chemical screening experiment to probe the PET decomposition mechanism involving in situ generated methanol and lithium methoxide from dimethyl carbonate, one of the most common #electrolyte #solvents in lithium-ion cells.
