During Admiral von Essen's expedition, the main force of the Swedish navy was conducting exercises in the Stockholm archipelago. Admiral von Essen sent a destroyer squadron that was to mine the southern aproaches to the Stockholm archipelago - if the operation continued, it might have encountered the main force of the Swedish fleet and suffered badly since they were carrying mines on their decks. They were to attack lighthouses, telegraph stations and lay mines that woudl sink any ships retreating damaged from Fårösund.
Fårösund itself at this time had 8x57mm M/92 guns and 6x17cm M/69 (of which only 2 were ever manned since they were hopelessly outdayed) protecting two mine lines. I have a hard time thinking Fårösund can do any kind of damage to von Essen's squadron, as he can easily stay out of the range of the guns and away from the mines and still pummel the coastal station and the single old steam screw sloop.
Sweden entering the war would mean 10 or so less Russian divisions on the Eastern Front at all times - which would probably mean that the Ottomans and Austro-Hungarians suffer less. If the Austrians do not lose Przemysl, they will be in a MUCH stronger position, which might convince Italy to stay out. And if Italy stays out, Austria-Hungary is stronger still, which will probably butterfly the defeats in the Brusilov offensive - Russia doing much worse might cause Romania to choose the Central Powers and go after Russia for Moldavia rather than Austria-Hungary for Transylvania, which would help the Central Powers situation immensly.
