Why open a tablet? Common reasons and risks
Before continuing, it is good that you consider why you are about to open your tablet and what you should consider before:
In general, it is decided to open a tablet to: repair a component, change parts, dry any possible moisture, clean the internal parts or make an assessment of a specific problem.
This, of course, is the case with repair shops: at home, unless we have a technician, we will just dust or see if there is any noticeable problem, to buy the part ourselves and try to install it.
These actions, of course, entail several risks, which will have a variable impact on your pocket:

How to open a tablet step by step
The first thing you should know before going into details about how to open a sealed tablet is that, if you choose to do it without tools, it is best not to use sharp and metallic objects for it: say knives or blades screwdrivers.
Unless you don’t mind leaving marks, it’s best to use some thin acrylic card or some other object similar to a guitar pick . The other important thing is that even if you think you have everything to disassemble a tablet without screws , you still need to have a screwdriver at hand, because sometimes the part of the tablet that has the USB ports, headphone ports, etc. it may have a screw that, if you forget to remove first, could hopelessly break the case as well as any sensitive components.
Now yes, let’s see how to open and disassemble a tablet step by step:
1. Create a master template if there are screws
If your tablet has screws, before opening it, mark its edges on cardboard, which you will then cut out, and which will serve as a master template.
This template has the function of serving as a guide on the location of the screws because if you then place one incorrectly in the wrong hole, you could end up damaging a component.
2. Use paddles and picks for leverage
Plastic trowels and picks are the quintessential professional tool in device repair shops: they will help you pry open your tablet (but always gently and patiently).
If you don’t have these types of instruments, use an old magnetic card, or something similar. We advise against the use of metal objects, but if you don’t care how the tablet looks later on an aesthetic level, you can use a flat blade screwdriver with a very fine tip.
Be very careful with aluminium cases, because the front part could be plastic and prying can damage the panel and touch.
3. Beware of FLEX cables
FLEX cables are flattened, flexible cables that connect the touchpad to other parts of the device, and if you pull on the tablet case carelessly you could easily break them, as is the cable that connects to the speakers, which is much thinner.
That is why you must begin to remove the back carefully and identify the type of connectors that the FLEX cables have, because depending on this detail, you will know if they can be released by pressure, a tab or in a sliding way. Never, ever pull on any cables inside your tablet!
4. Disconnect the battery
Almost all tablets (not to generalize), have an integrated battery. To avoid any type of accidental short circuit that causes a breakdown, you must disconnect it. The same removing the connector, that unsoldering it if that possibility does not exist.
5. Be very careful with the antennas
The antennas of a tablet, corresponding to Wi-Fi, Bluetooth, GPS, etc. are usually made of ceramic or adhesive material, which is almost always in the form of a sticker.
You must avoid puncturing or scratching them at all costs, because later you will have coverage problems in the different signals.
How to close the tablet when finished?
The process of closing the tablet also requires a certain dexterity, since not a few people have caused irreparable damage to their device, due to not being careful enough.
If the entire tablet is plastic, you can close it by pressing it between your fingers. Now, if the lid is hard, you’d better place it on a flat, clean surface . Place the screen against the table, and start pressing the lid from above so that it closes.
This is safer than closing the tablet between your fingers, which can bend and break the touchpad.
