Odds are overwhelming you will never solve a block solo mining at that rate.  Join a pool.

Using your laptop you are CPU (Central Processing Unit) mining.  A 5 year old laptop is probably a Core Duo or similar unit.  If you are mining with the Lite Coin Qt, then you will probably go the rest of your life without finding a single coin because you are solo mining with a toothpick (metaphor....).

A GPU is a "Graphics Processing Unit" also known as a graphics card. 

The software for mining CPU and GPU are different programs. 

The first time I synchronized my LTC wallet it took a couple days.

2KH/s?  Wow...that's about what my iPad Mini does... Often it doesn't even show up on the pool stat page.

The secret to mining is going to be computer power, either a lot of CPU or GPU.  Old single core CPU's (like a P4) just won't be worth the electricity they take to generate any shares to a pool.  I have a couple of dual processor servers with about 24 cores each generating close to 200KH/s when they aren't being used for actual work. ;)

Look for a Radeon HD video card or more to get into mining.

First answer: YES.  You need somewhere to keep your mined coins.  If you join a pool, your coins will be in your pool account until you're ready to do something with them.  I recommend putting a digital wallet on one of your personal computers.  Download a wallet from [size=78%][/size]

The easiest way to get started mining LTC is to join a pool.  There are plenty of them around. I use, but I have used a few others.  When joining a pool, you will set up "worker accounts" for each of your miners. I have a different worker account set up for each machine's GPU mining and CPU mining operations.  That's how you'll add additional computers.  You set up your account and point the software on each machine to the pool.

You are correct that nVidia cards are not really suited for mining cryptos.  When I first started to build my first miners I found the "LiteCoin Mining Hardware Comparison Guide" invaluable. 


Litecoin mining / Re: Low hash rate on 7970
« on: July 27, 2013, 04:18:01 PM »
I too had a shock when I moved from BTC to LTC mining.  When I looked at the average Pool speed for LTC and then my average hash rate for BTC I thought I was going to mine 50 LTC a day!

However, that isn't the case as you have already discovered.  It has to do with the way your miner actually produces shares towards each block.  BTC uses a completely different algorithm than LTC.  BTC uses sha256 algoithm and LTC uses scrypt (which is why you have to have a different mining software).  I'm using 7870's and my hash rate dropped from 600Mh/s per card to 270Kh/s going from BTC to LTC.

Now, to address what your card should be doing verses what it actually does.  Using the LiteCoin Mining Hardware Comparison the 7870 should be hashing out 350Kh/s.  However  anytime I attempt to actually use the settings suggested my machine reboots after various periods of time.  I will say that the motherboard seems to affect the performance.  My cards in AMD based boards produce more hashes than my Intel based ones. Also, the amount of RAM both on the GPU (on the 7870 there are 1GB, 2GB, and 3GB versions) and the system RAM.  Other factors include cooling of the system and the PSU.  I got a significant boost to performance when I moved to open air cases and 1500 Watt gaming PSU's.
