I'm in the trade, and as the previous guy said...there is a flurry to buy up 2-4 year old laptops from Gumtree and ebay, remove hard drives replacing with SSD drives, loading them up with the latest Win 10 OS's and charging serious bucks!
Currys best deal at the mo is an HP i3 8GB ram + 256SSD Win 10 for £450...Last January, this same laptop could be bought for £320!
I prefer John Lewis for anything electrical as their warranty is for 2 years...but at the mo, they are out of stock of almost everything...
So next best thing is to buy an i3/i5 second-hand Laptop. Remove the old mechanical hard drive and replace with an SSD Hard drive...you can pick up one 256GB "Pioneer" from Amazon for about £35
These drives are 5X quicker than the old style hard drive...making an old laptop a spring chicken again! look on Youtube on how to open up specific models...
Loading up the latest Windows onto your new hard drive....
((You can use a Windows 7 Product key, normally found underneath laptop... to activate a Windows 10 OS) Win 7 home = Win 10 Home etc)
Win 10 install can be downloaded from
https://www.microsoft.com/en-gb/software-download/windows10
this download contains both Win 10 Pro and Home. Once downloaded, you'll need an 8GB usb stick ...follow instructions and the way you go...if you need more advice on reloading a laptop, pm me.
When looking at a second hand laptop to buy, look at the mouse pad and keys...if they are shiny as F**k leave it alone....it's had a lot of use...our finger pads cause a lot of wear!
Listen for fan noise...it should be present, but not chugging...that would be another sign of overuse/very dusty environment.
A gentle fan flow on the face is good...feel the laptop for heat after leaving on for 15 mins....if it's hot, hand it back...clogged fan or poss a graphics chip overheating = nightmare!
I prefer 4th Gen i5's which still have plenty of guts (processing power) paired with an SSD drive usually starts Win 10 in 5 secs.
If for schooling, get the kids at least 15'6 inch screens...the 14" versions are very small font, and not good for kids eyesight let alone 45's+
Pm me if you need any free advice, hope this is of some help...
