One Reddit denizen posted: “I installed this on a Legion 7 16ACHg6 I’ve had for 7 months. After playing games for 10 min or so the laptop severely throttles for a couple of minutes.

Analysis: Avoid the replace, then? You may do, however that comes with its personal dangers
First off, we must always be aware that there are of us on these varied Reddit (and different) threads who've reported putting in the GKCN53WW replace with none issues. So, it would simply be a comparatively small proportion of Legion house owners who've hit bother with this BIOS replace – we will’t know the precise numbers, after all, however the variety of threads on Reddit counsel that this isn't a uncommon incidence, a minimum of.
Therefore the most effective plan of action may very well be to provide the GKCN53WW replace a swerve for now, arguably; however that mentioned, these aforementioned BIOS vulnerabilities should not one thing you wish to depart hanging round. However, you do not want GKCN53WW to repair these, as per Lenovo’s safety advisory on this matter, these holes are resolved by updating to GKCN51WW (in addition to GKCN53WW).

Hopefully Lenovo will repair this BIOS replace quickly sufficient, however we haven’t heard something from the producer but – and meantime, you’re left with the difficult selection of whether or not to improve and likelihood the crashes, or stick and threat the vulnerabilities as an alternative. (If you’re on GKCN51WW and managed to seize this model earlier than it disappeared, we’d counsel very firmly that you simply keep it up for now).
If you do replace to the most recent BIOS and encounter issues, Windows Latest highlights which you can roll again to the earlier BIOS model, which is now GKCN50WW: it may be downloaded instantly as an EXE file right here (however after all this doesn't have these very important safety fixes).
To roll again the BIOS in your Lenovo laptop computer, simply double click on on the EXE file of the earlier model you want to set up, and observe the directions given by the wizard that pops up. You might must allow the flashing of the BIOS to a earlier model earlier than you'll be able to roll it again, although, which is finished within the Lenovo BIOS Setup display – to get into that, see the directions right here.
Once in BIOS Setup, there’s an choice which is expounded to rolling again the BIOS model, and you must allow this (be aware that on some Lenovo machines, there generally is a rollback prevention choice which is enabled by default – and on this case, to revert to a earlier BIOS model, you must disable it).

All in all, it’s not an ideal state of affairs for the much less tech-savvy Lenovo laptop computer house owners on the market, who might not wish to mess with BIOS rollbacks, however may really feel compelled to take action, if any put up-replace crashing points are actually unhealthy. And certainly they could effectively really feel it’s finest to sit down tight on an older BIOS to keep away from this situation – understandably – however that’s hardly preferrred from a safety perspective, both. So, hopefully Lenovo might be wanting into fixing these reported issues as a matter of precedence…
