Second, while downloading the blockchain, hardly I can do other things (even though my laptop is not that bad)!

If it's similar to the HDD access issues I've experienced with the latest version, and you don't have an SSD, a decent solution is to do the initial sync with the "chainstate" directory linked to a RAM drive. When it finishes, copy the results to phyical HDD.

If it's a CPU issue, try limiting BitcoinCore to a single CPU core. You can also lower its process priority from the Windows Task Manager: right click a process and use "Set Priority". In Windows 8 and later it's in the "Details" tab.

Exactly! That's why I think I don't have to buy those tiny excellent Raspberry Pi 3 Model B, or the Bitseed computers (yet) to run my full node.

Okay, I became curious enough to measure an Ivy Bridge laptop.

I got 14-36W. 14W with very light load and screen off. 36W with CPU maxed and screen on. Didn't check the effect of HDD activity. The measurement accuracy may be off, especially at the low end. The laptop's battery was connected, but not charging. I don't know the efficiency of the AC/DC adapter.

I used to run the full node on my workstation. But since I switched to a laptop (much more handy for what I do at the moment), I cannot do that any longer.
First, it will take ages to download the blockchain;
Second, while downloading the blockchain, hardly I can do other things (even though my laptop is not that bad)!
That is a shame I cannot keep doing it!
Would you have any solution?

p3ppymon,
Possible solutions:

1) You may download the whole blockchain at once from my Google Drive (see details in https://bitcointalksearch.org/topic/whole-bitcoin-core-015-blockchain-database-on-google-drive-2321650

2) You may keep a pruned blockchain (personally I have never tried it)

3) while downloading the blockchain you can be safely doing any other things with your laptop! Process, CPU, download bandwidth will be busy 3-20% only.
Besides, on windows you may use any advanced task manager (I use http://systemexplorer.net it's free) to set the process priority, etc. for the Bitcoin Core application to even more reduce its hardware requirements.

My laptop consumes not more than 60 Watt even at peaks.

Assuming full nodes don't use much CPU on average, and mostly just serve blocks, I think a laptop for this usage would more likely consume 10-20W.

Is there a geographical map of where nodes are? I have a 300/300mbps connection - and a Ubuntu installation. Is running a node hard on the disk? Is 500GB disk sufficient? Sound like it. Can I install the node software and let it rebuild of the blockchain?

.
500 gb is absolutely sufficient. If only you can, do install and launch your full node as frequently as it's possible for you! If you also allow incoming connections and open 8333 port (either by port forwarding, or enabling UPnP in your router) that will be just great!

The full nodes map and your 8333 port accessibility can be found here for example :

you can check https://bitnodes.21.co I'm not sure there is an actual map but it shows nodes around your location.

That is a really good question!
Is there any way to know where nodes are, and what is the best server to launch one more node?

I don't quite see the benefit of run your own full node.
Aren't the miners already providing the needed computational power to verify the transactions?
What am I missing here?

Mining - computational power for processing of the transactions.
Full node - a complete copy of the Bitcoin ledge, that miners read and write against. Full nodes ultimately "vote" which chain is perceived as main by the miners.

Having a full node running is a very good idea - that is one of Satoshi's visions behind the decentralised nature of Bitcoin.

I have had one running 24/7 since I first acquainted myself with Bitcoin. Currently the blockchain database uses 150GB (I have it on a dedicated 238GB SSD disk, dimensioned for growth).

That's right, straight to the point if run Core full node just for avoid B2x hard fork, 10 minutes will be enough.
I would like to run Bitcoin core someday when I have new pc, but for now I don't have enough space disk to storing a copy of the blockchain.

I do not agree, but naturally, you have the right to have your opinion

Bitcoin will be just fine, you are being paranoid. Running a full node always helps the network, it won't do anything special now. It isn't a voting system, it doesn't matter when it comes to forks. There might be a bit of lost connections during a fork as nodes start following different chain and disconnect, but this will last for a very short time and if you want to help for this purpose only then just run it during those 10 minutes when the fork happens.

Look at the recommended minimum requirements for Bitcoin core full nodes:
- At least 145GB disk space
- Download capacity of 500MB/day (15GB/month), plus a one-time 140GB download the first time you launch Bitcoin Core
- Upload speed of 5GB/day (150GB/month)
- 1GB RAM
- Desktop, laptop, or compatible ARM chipset
B2x hard fork will be live on October 16th, right? But it seems 2x supports continues to decline over time.

This is actually new to me about running full node on a computer just to support the Bitcoin community. For what? What are the benefits of running 24/7 that costs power but what in return? I guess big mining companies are doing the same way since they have top of the line hardware.
I wish one day I could get my hands on the work to experience this Bitcoin core personally.

As bitcoin fan pointed out, there's no monetary reward for running a full node. But you do get the chance to not only contribute the system by verifying transactions and you also get the best security if you link your wallet to your node.
I have a question for you bitcoin fan. Do you think buying a bitseed core would be a good purchase? It's online 24/7 by itself and it would save me a lot of hassle keeping a laptop running 24/7.

If I were you I would just buy a Raspberry Pi and configure a Raspnode. In fact, this is what I am doing right now, I also have a Bitcoin Core node on a Pine64.

http://raspnode.com/diyBitcoin.html
good luck

Thanks for the suggestion. I've heard you need to be a little bit more technical for a pi but I think I can manage. Purchasing a pi would actually be very convenient since I am in the need for a raspberry pi for something else as well. I'm going to do some digging on both the pi and the bitseed and hopefully purchase whichever fits me best.

It is really a good thing to support the Bitcoin network by running a full node, I am doing that too. the problem is that Bitcoin core needs a huge free disk space which is not available for every user, also downloading Bitcoin core takes too long especially if you don't have a good Internet connection, it may take days or even weeks to be completely downloaded. But it is nice to remember others how important it is to be part of the Bitcoin network.

I've quickly read up on this.

Mining has gotten more and more centralized because it nowadays requires specialized hardware and significant investments.
Each running their own full node would protect the bitcoin network against being hijacked by a group of miners with bad intentions.

Is this your main concern and the reason you'd want everyone to run a full node?

Not only.
The more full nodes, the more reliability, speed and fault tolerance there will be in the whole Bitcoin network ecosystem.

And the more people in the whole world would actually perceive the Bitcoin as the best and most reliable, TRUE money that they really accept, value and fully trust!

... The energy consumption is about 10 watt while a laptop consumes 90 Watt, in this way you save cost for the energy. Building a Node on Raspberry Pi is the same as a Bitseed and the costs may be the same.

My laptop consumes not more than 60 Watt even at peaks. So laptops, netbooks, those excellent little wonderful computers like the Raspberry Pi 3 Model B, or the Bitseed, choose which ever you may afford!
Just set it up sooner and run your full node!

You are missing so much, that I'd ask you just read this for start:

https://en.bitcoin.it/wiki/Full_node

Believe me, if only you can, do start running your own Bitcoin Core full node!
