Hey peter, there's a good chance it'll be OK.
Before this Windows 10 new power saving mode called "Modern Standby", it was possible to turn off most power saving routines in the normal OS settings. (right clicking power icon and choosing those settings, advanced settings etc).
But looks like the new Windows Modern Standby mode may only "properly" be turned off by going into BIOS settings now (unless there are updates to come - different ways to do that on boot-up, sometimes holding F12 key and others - each PC could have differences, like maybe needing to do Ctrl+Alt+delete after power on, then a key like F12, or F6 depending on brand/model - easy to check that when you know which PC though). What's not easy to find out, is what is in what BIOS settings in different models.. many manuals only give basic info, like how to change an admin password in BIOS and mention nothing about what things can be altered. Some BIOS config settings can be minimal, others really detailed, some have both a basic and detailed display enabled by selecting a toggle in there.
There's often a similar setting to disable power saving in the BIOS of most PC machines (at least I don't think that's changed yet), with different makes having some differences (like Lenovo T14 Thinkpad's interesting wording in BIOS choice between Windows and Linux power modes) - I've had no luck yet finding specific info about this on various cloudbooks available so far - I guess because many who buy them want power saving mode on rather than turned off and they're not online asking how to turn off Win 10's "Modern Standby" mode in the BIOS, yet. (or my "search foo" is weak today!)
Just a wild guess at this stage - but I think there really should be a make and model of cloudbook with the ability to do similar to the above with the Lenovo T14 Thinkpad (some different makers of cloudbooks will be kind about these things I hope while it's possible others head for the future without regard).
It might mean your best bet would be to make a visit to a retail PC outlet and a chat with a tech savvy sales person who might hopefully boot into BIOS for you while you watch to check for sure on a specific machine you're into
Hope this didn't cause too much undue panic just yet! But I don't like how sometimes these changes just happen and we're all left wondering "Will it work ever again".. kind of still feels crazy to me a day or 2 after seeing that issue, that something like that can be limited in that way for new Windows 10 users. I get "save power".. but it's not feasible doing audio work with low latency etc.. but it's hopefully work-around-able!
