When repairing a junk computer, the first thing to do is to remove the back cover.
If you can’t remove the back cover, you can’t repair it.
However, there is a big obstacle standing in the way of repair.
That’s right.
In many cases, the screw itself has collapsed and it is impossible to even open the back.
I’ve tried everything, and if you do this first, the screw thread that stripped will come off 100% of the time.
The first thing to try is to insert a rubber band into the screw and turn the screw.
The rubber band will bite into the screw hole and turn it, but this will not work at all on a completely screw thread.
Another method is to apply a tube of liquid to the screw hole and remove it. The liquid contains something like sand, and if the screw can be fixed to the screwdriver, it may be possible to turn it, but like rubber bands, it is completely ineffective for completely licked screws.
There is a last resort, and it takes patience and time, but it will turn the screw 100%.
We will show you how to do it.
What to prepare
Electric screwdriver
It is impossible to do this by hand. Electric screwdrivers are expensive, and I know you don’t want to spend that kind of money to turn one screw, but a cheap one will do. I bought an electric screwdriver that cost less than 2000 yen(20$).
Anex Tanned Screw Remover Bid It is best to use a screwdriver with lubricating fluid.
For laptop screws, I use a red M2.5 to 3 screw remover.
The whole point is to recreate new screw holes.
These Anex unscrewing bids are the best, and they are made in Japan.
It has a drill part and a threaded part on both sides.
The drill part makes the screw holes little by little so that they rotate to the right.
This process takes a lot of patience and effort.
Keep calm and drill the screw holes little by little.
It is a good idea to use lubricating fluid. Drill the holes vertically in a right-hand turn.
You should be able to drill about 1 mm. You can use a lot of force, but I think it’s better to trust the electric screwdriver and do it slowly and carefully.
Even if you can dig a little, you will break the screw hole, so if you can dig more than 1mm, you will see that the screw hole has been made.
It takes a couple of hours to dig a millimeter, and you have to take a break every now and then.
Once you have dug out more than 1 mm, replace the screw bid of the electric screwdriver with the opposite screw part and turn it to the left this time.
Once I know that the screw bites and turns, I try to open it by myself, vertically, turning left.
This is because it is easier to see the bite of the screw manually.
If I put all my strength into it and can turn it to the left even a little, the screw will open.
It’s only a screw, but if it doesn’t open, you won’t be able to go on, so try your best.
The moment when the screw turns and the screw is removed is a very moving moment.
The screw that has been removed is no longer usable, so replace it with a new one.
The size of the screws may differ slightly depending on the specifications of the computer, so you can take the screws to a home center and buy the appropriate screws.
By the way, the screws for Toshiba’s Dynabook R63 series are M2.6×8, and they cost about 100 yen for a pack of 10 screws.
