The situation when the screw holding the cover or inner panel breaks the thread or licks off the edges under the influence of a screwdriver is one of the most common problems when repairing equipment yourself. Owners Asus, Acer or Lenovo often face the need to disassemble the device, but cannot do this due to stuck fasteners. Ignoring the problem or trying to brute force it can lead to cracks in the plastic case and damage to the motherboard.
Removing such an element requires patience and the use of specialized tools, since a standard screwdriver no longer provides the necessary grip. It is important to understand that every action must be balanced so as not to aggravate the situation and not turn minor repairs into the need to replace an expensive chassis. In this article we will look at the most effective ways to solve this problem.
Preparing tools and assessing the extent of damage
Before taking active steps, it is necessary to create the right conditions for work. The lighting should be bright and directed directly at the problem unit, since the slightest mistake when pressing can lead to the tool sliding deeper into the body. You will need a set of precision screwdrivers, tweezers, a magnetic stand, and possibly chemicals to penetrate the threads.
Assess how badly damaged the edges of the screw are. If they are only slightly flattened but still have shape, you may be able to use a smaller tip screwdriver or rubber washer. If the cross or hexagonal profile is completely erased, a more radical approach will be required, including drilling or the use of extractors. Do not try to use a drill right away as this may damage the backing underneath the screw.
First, check to see if the screw is jammed due to corrosion or hardened glue. Sometimes a small amount of penetrating lubricant such as WD-40 or similar composition, and wait 10-15 minutes. This will soften the dirt and make it easier to rotate. Remember that harsh chemicals can corrode the plastic of the case, so apply them point by point.
Gather all the necessary tools in one place to avoid distractions during the process. Having a magnetic mat will help you avoid losing small parts if the screw suddenly comes loose. If you plan to use heat, make sure there are no sensitive electronic components nearby that could suffer from overheating.
Mechanical methods using rubber and rubber plug
One of the simplest and safest methods, which often works with minor damage to the edges, is the use of elastic material. Take a thick balloon rubber or a special rubber stopper and place it on top of the stripped screw. Press the screwdriver firmly through this layer of rubber and try to slowly turn it counterclockwise.
The rubber fills the voids in the cut edges and creates additional friction, allowing the screwdriver to grip the screw. This method is especially effective for screws that have not been over-tightened. If you use regular rubber band, make sure it is not too thin or it will break under stress. Anti-stall here is ensured by deformation of the material.
Sometimes using a piece of foam or felt helps, which also creates a seal. The main condition is the maximum pressure of the screwdriver on the screw head during rotation. Do not make sudden movements so as not to completely cut off the remaining metal. If the screw does not budge after several attempts, move on to more advanced methods to avoid ruining the seat.
⚠️ Attention: When using rubber gaskets, be careful not to allow material to enter the housing through the ventilation holes. Use tweezers to remove remaining gum after surgery.

Using adhesive for fixation
If the screw has damaged edges, but its head protrudes above the surface, you can try to fix it with a screwdriver and superglue. Apply a drop cyanoacrylate glue onto the end of the screwdriver and press it against the screw. Hold the tool still for the amount of time specified by the adhesive manufacturer to allow the joint to fully cure.
This method requires perfect precision, as misalignment of the screwdriver can cause it to stick to the laptop body, creating new problems. Use a minimal amount of glue so that it does not spread over the surface. Once cured, try to slowly unscrew the screw using moderate force. The method only works for screws that are not tightly jammed.
Try it first on an unnecessary fragment or in an inconspicuous place. If you use this method, make sure that the screw does not turn inside the threads, as this may permanently strip the threads in the laptop case.
For reliability, you can use epoxy resin, but its hardening time is much longer. Epoxy provides a stronger bond, but requires careful application. Do not use this method if the screw is too close to sensitive components, as the chemical fumes may harm them.
Drilling and using extractors
When simple methods do not help, you have to resort to drilling. This is the most difficult stage, requiring the use of a micro drill and a set of metal drills. Start with the smallest drill bit and carefully drill through the center of the screw. Try to hold the drill strictly perpendicular to the surface so as not to damage adjacent elements.
After creating the initial hole, increase the diameter of the drill gradually until you reach the base of the thread. Be extremely careful not to drill all the way through the laptop body. Depth control drilling is a key success factor. Use a depth stop on the drill if available.
If you have a set of extractors (reverse drills), insert them into the drilled hole and begin turning counterclockwise. The extractor cuts into the metal of the screw and unscrews it. This method is effective even for completely stripped screws, but requires a steady hand. Take your time, take breaks so that the drill does not overheat.
| Method | Complexity | Risk of damage | Tools |
|---|---|---|---|
| Rubber gasket | Low | Minimum | Rubber, screwdriver |
| Superglue | Average | Medium | Glue, screwdriver |
| Drilling | High | High | Drill, drill bits |
| Extractor | High | Medium | Extractor, drill |
☑️ Check before drilling
What drills are best to use?
For stainless steel screws, pobedit drills are needed, while for soft alloys, regular HSS drills are suitable. Using a dull drill increases the risk of slippage and damage to the housing.
Thermal method and exposure to a soldering iron
Sometimes a screw becomes jammed due to oxidation or hardened sealant, and in such cases, heat can help expand the metal or soften the compound. Apply the soldering iron tip to the screw head for 10-15 seconds. Heat will expand the metal and the gap between the screw and the housing may increase, making it easier to remove.
This method is especially relevant for screws coated with varnish or paint, which are used in some models Apple MacBook or old Dell. Heating will soften the varnish coating, making the screw easier to turn. Do not overheat the screw so as not to damage the plastic elements of the housing or thermal pads nearby.
After heating, try to unscrew the screw using a screwdriver with a rubber gasket or an extractor. Heat reduces friction in the threads and helps break down the structure of hardened contaminants. If the screw does not budge, repeat the procedure, but do not hold the soldering iron for too long to avoid deformation of the parts.
It is important to use a temperature-controlled soldering iron to avoid exceeding the heat limit. For small screws, a temperature of about 200-250 degrees is sufficient. If you are not confident in your abilities, it is better to entrust this operation to professionals, since the risk of overheating the motherboard is real.
⚠️ Attention: Never use an open flame or a hair dryer at high temperatures, as this can melt the plastic of the case and damage the laptop display.
Before starting to work with a soldering iron, unplug your laptop and remove the battery to avoid short circuits due to accidental contact with the board.
Alternative solutions and when to contact a specialist
If none of the above methods work, it may be worth considering alternative options. Sometimes it is easier to remove the entire module in which the screw is stuck, if the design allows it. In some cases, the screw can simply be pushed out from the inside if you have access to the back of the case. This may require complete disassembly of the device.
If the screw is in a critical place, for example, holding a processor or video chip, it is better not to risk it and contact a service center. Professionals have access to specialized equipment, such as laser cutters or ultrasonic baths, that can solve the problem without risk.
Some craftsmen use the method of cutting new threads for a screwdriver using a needle file or drill. This requires high skill and is only suitable for screws with sufficient head height. Errors at this stage may render the screw unusable and require replacement.
As a last resort, if the screw does not interfere with the further operation of the device, it can be left in place by gluing or fixing it in another way. However, this is not recommended as vibration may cause loosening and damage to internal components. The decision always depends on the specific situation and laptop model.
The main goal is to remove the screw without damaging the case. If these methods don't work, stop and call a professional to avoid costly repairs.
⚠️ Attention: Never use excessive force when attempting to remove a loose bolt, as this may cause cracks in the chassis or damage to internal components of the laptop. This is the most critical rule that will help keep your equipment intact.
