Guidance for extended backup, please?

Yeah screen size depending of course. 65 would use more than 55 for example.

52" and I checked the Laptop is about 65watts, thats why I figured the total of 100-120 watts, but yes, I will go for higher to be certain.

Exactly.

And as much as I'm not a fan then it's worth looking at using the Energy Saver stuff or altering the brightness, maybe even making a Load Shedding "profile" to switch to.

Yeah sometimes I run eco to drop it below 100

If the laptop is 65w - you’re going to be using a lot more than 100w - closer to 200w.

Is the laptop battery shot?

I’ve never bothered to use power saving features on the TV. All or nothing lol

Yeah sometimes it's fine, but during stage 6, prefer having power longer, then the image being a bit brighter.

52" doesn't really give make or model :-P also 65w for the laptop, which is the peak it will use, so more or less it will be 30 to 40w + the TV being a 52" if LED would be 75w by itself, if it's LCD it will be 150w

Don’t you have solar / batteries?

The only thing I change when it’s Stage 6 - is put the house into “back up“ mode during the night. Meaning I don’t drain the batteries overnight. So, a 4hr slot of no power makes zero difference in my life. TV, lights, even kettle usage.

No - but it is a case of size vs battery life. It is a powerhouse packed into a slim notebook. So the battery lasts about 90 minutes. I know, pretty useless, but carrying the thing around when I travel, is a breeze, and worth it

Right, so if the battery is fully charged at the time when you are LS - power draw from it will be minimal when plugged into an inverter / battery setup.

Yes that makes sense. I suppose I could also unhook it until the inter battery is exhausted and then hook it up again. 90minutes of no usage at all.

Not really no. A typical modern TV will consume between 50 to 100 watts and a laptop has its own battery, so just needs to be kept topped up.

Perhaps the laptop’s battery is fried ie it’s a desktop.

It's six months old, in pristine condition. Treated like a lady :-)

I did some test and my 55" does consume about 100w at 720p. But freaking hell, put on a 4k movie and then it goes to about 300w :p
 
Fully charged laptop will draw as much power as the laptop needs to run.
The batteries Wh rating, is not the Wh you'll get on the AC side.
AC will be less as a result of DC to AC conversion losses and inverter overhead.
