@Wersus Sì, e tale opzione comunque è disponibile ma nascosta: nel BIOS c'è una opzione che di base è disabilitata chiamata "BIOS Flashback" o qualcosa di simile.
Abilitandola, basta eseguire in teoria l'eseguibile di quella versione su PC per fare questo ritorno alla versione precedente.
Ovviamente non è abilitata di default poichè inusuale e potrebbe dare problemi non meglio specificati. Tuttavia una funzione integrata nel BIOS con la selezione dei BIOS precedentemente installati ( quindi senza andarsi a cercare il file ) sarebbe ottima.
@Wersus, sì, intendevo quello che hai capito: avere disponibili sul sito ufficiale anche almeno alcune le versioni precedenti del BIOS, per poter effettuare il rollback, che è consentito da Lenovo stessa.
Certo, la cosa migliore sarebbe che testassero meglio le nuove versioni del BIOS, eeeeh...
Ho controllato su Vantage e non trovo più il BIOS .53 nella lista degli aggiornamenti (l'unico aggiornamento che c'è da sempre è quello GExperience che non ho installato).
L'hanno ritirato dunque?

Sul mio lenovo legion lo avevo già installato
sul altro lenovo che ho preso (idea pad gaming 3) in effetti nel vantage non lo da disponibile
Mi sono ritrovato il BIOS v53 come update di Windows e non più su Vantage. E infatti, anche se volevo evitare, ora sono con questa nuova versione.
Al momento non sto notando particolari differenze. Penso che sia stato tolto perchè convalidato appunto su Windows e quindi spinto come update "urgente" per quelle vulnerabilità ( capitò anche per la v42 o v44, ora non ricordo di preciso quale, che migliorò la gestione dell'Overclock alzandone le soglie ).

Confermo la presenza, appunto da un paio di settimane, in aggiornamenti facoltativi di WU, di questo non meglio precisato ''firmware'' 1.53.0.0 Lenovo. A me fortunatamente ancora non l'ha installato di testa sua (W10 Pro), ma con WU di certo il pericolo non è scampato. Anche se su un vecchio portatile ho da anni degli aggiornamenti facoltativi (driver) che stanno ancora là.
Questo però chiude una falla importante e quindi potrebbe forzarlo.
Ma soprattutto, da quando i BIOS si possono installare via WU? Non sono aggiornato io?
Cmq poi il 2 giugno è uscita la versione 54 sul sito, ed ora la vedo anche in Vantage.
Tu l'hai installata? Pare che cmq non risolva le BSOD casuali quando il portatile è più o meno n idle e alimentato a batteria, introdotte con la ver. 53.
Non ho capito se le BSOD cmq riguardano solo i Legion 5 lisci e non i Pro.
Infine, per la questione fonte affidabile per i vecchi BIOS, mi hanno suggerito semplicemente di cambiare il numero di versione al link per scaricare l'ultimo BIOS sul sito Lenovo. Mi sono salvato la 46 (su cui sono ancora) e la 49.
La 51 però non c'è più: lol, da quel che avevo capito, era quella che risolveva già le falle di sicurezza, ma non introduceva le BSOD; anche se alcuni avevano lamentato aumenti di temeprature con la 51.
Mentre posso scaricare una .50 che non sapevo manco esistesse. Evidentemente non era per noi. Occhio che si possono fare casini.
PS: a proposito degli aggiornamenti automatici dei driver, di cui dice sotto WU, nell'ultimo mese si sono aggiornati due volte quelli relativi alle funzioni Fn, senza che né sul sito, né su Vantage abbiano caricato queste nuove versioni.
E' un bel casino in generale seguire gli aggiornamenti...
@Deki
Riguardo WU penso che sia appunto per la vulnerabilità che vengono spinte queste versioni, e ho visto della v54. Da quel che ho letto nel Discord dei Legionari non tutti hanno avuto i problemi di BSOD ( io non ne ho avuti ) ma so che ha riguardato sicuramente i 5Pro ( e penso quindi tutta la gamma perchè la famiglia Legion a livello hardware è quasi identica ).
Io al momento sono tornato alla v50. Perchè? Eh, racconterò su questo forum di una mia epopea personale dove il mio 5Pro è diventato il laptop di Teseo e dell'originale non è quasi rimasto nulla ( e darò anche delle utilissime raccomandazioni per i posteri ). In sostanza, alcune schede madri escono con la v50. La v51 durò pochissimo ( circa 2 settimane ) e forse per questo non è disponibile.
Al momento comunque non aggiorno, anche perchè voglio assicurarmi che il PC funzioni dopo queste riparazioni. Ma ehi, perlomeno adesso ho la VRAM Samsung 🤣
A quanto pare la versione 54WW è stata rimossa da un pò, anche io l'avevo installato, ma il problema della schermata blu ce ancora purtroppo,io vorrei sapre che cavolo hanno combinato quelli di lenovo e perchè non ci danno nessuna notizia mah
Proprio oggi tramite lenovo vantage ho installato , in quanto disponibile , il bios versione .54
mi sembra sia andato tutto a buon fine
ho un lenovo legion 5
Grazie della conferma! Appena torno al PC guardo anche la mia versione (funzionante) così possiamo tenere traccia di quali release siano consigliabili e quali meno.
