How do I calculate how much energy laptop will consume if run 24x7 ? I know the question is subjective and people may say it depends on what activity is happening, is it laptop idle or running high end game. But still is there a way to know?
Mine is a Lenovo Laptop and does not have a screen so my intention is to keep it running and remote (teamviewer) via another laptop when I want to do something.
My laptop is having charger of 65W if that helps.

I want to then calculate how much may be running cost if I go this route.

This was as per 60W calculation. 43Units in a month or so...

This is the maximum it can consume. Depending on the load on the laptop, actual units will be lesser.

Thanks. And yes maximum helps as at least gives me worst case scenario. In Mumbai, we have tata power (for our electricity vendor) and I will go through the bill and see wat we are charged per unit. The rates are different for say..

0-100
101-300
301-500
Above 500

I will consider the worst case here too but anyways I checked last 12 months bill and max has been 440 units we have been billed in a month.

Planning to mine with this laptop?

No. I tried for 2 hours once using Nicehash and it showed me profitability of $0.05 per day :) I am not into mining and stuff. I wanted to just try my hands at setting up a local PLEX / Jellyfin server and then use jackett / radarr / sonarr stuff. But I got to know that PLEX mobile app and TV apps do not have playback speed control so this actually means I cannot use PLEX at all. I watch stuff at minimum 1.20x speed and increase it as desired.

I was going through articles and videos on how to mine. I have gtx 1080 in my main desktop and 3 more old laptops which are lying around. Its not worth the hassle and electricity cost to mine using laptop cpu To get 0.05$
 
It won't consume 65W 24x7 like someone said above, it'll be much less. If you had one of those devices, kill-a-watt-metre I think it's called you would get the exact reading. I bought a couple of them long long ago from some Meco brand.
 
Running costs of laptops is negligible. Probably something Rs 2 /day .
I have kill-a-watt like device. Trying it now on a thinkpad laptop, Its consuming 25W at idle with screen on and its also in charging mode.
 
If you are planning to use your laptop as a torrent downloader/seed machine then power usage will be minimal. And I would suggest setting up a static IP for your laptop via DHCP on your router so that you can use Windows Remote Desktop to connect to it. My Windows based file server operates that way.

Furthermore if you have qbittorrent then you can access the web UI of your torrent client on any machine on your home network through any browser e.g. I hit my qbittorrent web UI running on my Pi through 192.168.1.100:1340. on Chrome.

I used to run my file server (using a Atom mini-ITX board) quite a lot for downloading before I switched to automated downloads using the Pi. I upgraded to a Intel Pentium CPU on my file server since I don't run it that much any more as well as 6 SATA ports on a Z490 mini-ITX board.

The older Atom board with its RAM is lying unused along with my CoolerMaster Elite 130 chassis as I switched to a Fractal Node 304 for more HDD capacity.

That is nice to hear. If i can make it all work after spending on few hundred per year, I will definitely go for it. Lets see. Do we get a kill-a-watt like device available in india? Any links?

Its not subjective at all.
The easiest way to check this is with a a wall energy measuring plug - they are cheap and are a handy tool to have

Alternatively, use a tool within the OS to collect the power draw data (hwinfo can do that for example)
Sum it up - and bump up the watt-hour total by about 15% to factor in power conversion inefficiencies

I installed HWINFO just now and it shows CPU watts only. I searched online and thats true, it only shows how much CPU is using. I tested this and when Idle, it was 2W or so (so low?? or I read wrong) and then I ran a 2K video on youtube and it went upto max 7.XXW.

Btw you have any suggestion or link of wall energy measuring plug available in India?

Its not just CPU draw - it has a section for battery draw.
Run system on battery, set to max performance.. Use as normal to see the total batter draw in watts and then extrapolate

else get something like this

I ran a test on the laptop with qtorrent running in background , screen off.
Takes about 12-13 Watt . Which leads to 13*24 - 0.3 Killowatt hrs / day .

Bought one from amazon ages ago Rs 600-800.
Looks like this (but was some other item) - https://www.amazon.in/Magideal-MH_1...bd223&pd_rd_wg=08baf&pd_rd_i=B0747BY991&psc=1 .
 
Do things like connected USB HDD (4TB OR 2TB) cause the watt usage to spike up? I guess yes. And PLEX server while not actually being used may consume less watts but if streaming starts, I guess more watts may be used.

If you don't want to purchase an additional device, then HWInfo will indeed provide the best approximation. It monitors the battery where you can see the Current, Min, Max, Avg values of the remaining battery capacity.

Set your power plan to be the same as you use when plugged in, disconnect the charger, then reset the counter in HWInfo so that you can use the Max value as the starting point and the Current value as the end point whenever you want to stop.

If, for example, your battery capacity goes down by 10 Wh in 1 hour, then it means you are using 0.24 kWh or unit per day. Following is the tariff for Tata Power in Mumbai:

Yes, they do.. but only when in use as they will spin down after usage.
What gen/ type is your laptop? I can give you ballpark estimates on the basis of that
