Laptop Disassembly Tips

Precision Screwdriver Set

Here are a few tips that may help you strip down and reassemble laptops:

  • Use a digital camera or camera phone to take a shot of each stage of the disassembly for reference when you are ready to reassemble it. Zoom in and take separate shots for areas where you have various plugs and connectors or wires running in a specifc way so you know exactly how they were before you took them apart. (unless you have a really good memory!)
  • Use scrap sheets of A4 paper to map out screw positions. Sketch a point (or points) of reference like a battery compartment or RAM module cover on the paper so you know what way up it goes and stick each screw to the paper with clear tape so when you’re finished taking all the screws out of the bottom of the laptop they will all be stuck in their corresponding positions on the piece of paper. Depending on the laptop I may have 2 or 3 sheets of paper with screws on – bottom of unit, under the keyboard and motherboard screws. Doing this will be a great help if you have to leave the laptop disassembled for some time (e.g. to order parts etc) as you will have no doubt as to which screws go where. Some makes and models will use the same length screws for most of the base assembly but others have all different lengths which makes it all the more important to remember where they go back. A ‘too-long’ screw in the wrong place could cause major damage! Continue reading “Laptop Disassembly Tips”

Photoshop – Fill with colour quickly


Back in the day I used PaintShop Pro and I was really comfortable with it. During those years I had a brief fling with Photoshop 7 which left me feeling utterly confused with her seemingly counterintuitive tools.

One of those things I seemed to do really often was fill stuff with the Paint Bucket tool. In PaintShop Pro, this seemed to work as expected and I got so used to the way it works; you just set it to 100% Tolerance to fill the whole layer or selection.

The Paint Bucket tool just doesn’t work that way in Photoshop – in fact it is very similar to the Magic Wand – it just fills with colour the same way it would make a selection http://rxc..-viagra-price/. I had some retraining to do if I was going to grow up and move in with Photoshop…

I found out it’s actually quite simple to fill a layer (or selection) with colour in Photoshop – just hold down Ctrl and press Delete to fill with the Background Colour or hold down Alt and press Delete to fill with the Foreground Colour!

Photoshop is a powerful tool and a bit like my human brain;  I know how to use only about 10% of it.

Much of this is because there are lots of tools and techniques that I don’t use often enough to remember all the steps required to achieve a certain result.

Clicking the Magic Wand and pressing delete is easy. Some images lend themselves well to the Magnetic Lasso Tool. But there are some images that end up looking like you cut them out with pinking shears no matter how good your Lasso and Magic Wand skills are

Particularly troublesome are images where you need to cut around animal fur and human hair. The following is a dual tutorial that I found and bookmarked. Rather than using a layer mask, the author uses a colour channel and the burn tool to create a selection that really works well with the right images. Lets go!
