Notebooks: Changing the CPU involves a great deal of effort and risk. In some cases, the processor cannot be removed at all because it is soldered to the motherboard. Research the Internet for reliable instructions for your notebook model in order to be able to estimate the effort in advance. In any case, you then have to unscrew the device and remove the cooling system. Whether this is possible without removing the keyboard varies from model to model. You loosen the notebook processor by turning a screw (Intel) or pulling a lever (AMD). As soon as you hear a click, you can take out the old processor and insert the new one. If you face any issues you can take help computer store.
Install the mainboard in the case
Installing the motherboard is one of the more complicated tasks when assembling or upgrading a computer. While the overall installation process is relatively simple, you will need some standoffs and screws in the right place. And if something goes wrong, it can be difficult to pull the logic board back out. This is especially true when you are almost done with the installation and also need to remove some expansion cards that have already been installed. Before installing the motherboard into the case, there are two other things you should do. Install the chassis connector panel that comes with the motherboard and mount the CPU and cooler. Later, when the motherboard is assembled, you cannot attach the connector panel.
One of the most common problems PC builders encounter is related to the brass standoffs that come with most cases. Because brass is a relatively soft metal, it’s fairly easy to strip the threads. Make sure you only use enough force to secure them to the motherboard bay without slipping. Tighten the screws just enough to hold the motherboard without causing any vibration. There’s no need to over-tighten the screws and put unnecessary pressure on the motherboard. You should use as many standoffs as are designed for the motherboard. If you have extra standoffs under the motherboard that don’t match the screw holes, then you should remove them.
Insert a new bios battery
CMOS (Bios) batteries are always charged during device operation and should therefore last for many years. In secondary devices that are used less frequently, however, the small battery often dies too soon. This has the extremely annoying consequence that the device asks each time it starts up whether the user wants to start the bios setup or accepts the default settings. The bios have always forgotten boot and peripheral options, date, and time.
In PCs, after opening the case, the round lithium cell on the motherboard is easy to locate. The button cell can be carefully levered out of its small socket with a toothpick. Do not use any metal objects for this. After removing the old battery, insert a new button cell of the same type. If you are unsure, take the removed lithium cell with you as a sample when you buy it.
On many notebooks and netbooks, changing the battery, which is simple in itself, is unfortunately by no means effortless. Netbooks in particular often require the keyboard to be folded away and the components to be extensively removed, with the risk of disconnecting or even damaging fragile cable connections, for example to the display or touchpad. If you need to change the battery there, you should look for instructions on the Internet that match your model exactly or as closely as possible.
Insert memory modules
Replacing defective RAM modules is probably the simplest of all repairs. Memory is not expensive. All you have to do is fold out the side brackets, remove the old modules and then insert the new ones with gentle pressure until the brackets click into place. The required DDR generation (DDR, DDR2, DDR3, DDR4) and the clock rate of the motherboard can be determined in the bios, in the manual, or with Hwinfo (under “Memory”). Ideally, the modules have the same clock rate as specified by the chipset on the mainboard. Faster modules are not a serious problem, but then they work slower than they technically can.
In addition, the RAMs must be installed in the correct slots to ensure multi-channel operation. In the event that you mount the memory in the wrong slots, the system will probably still boot, but it may only work in single-channel mode. This would adversely affect performance. You should also pay attention to the height of the RAM. Many very powerful modules have relatively high heat sinks that may not fit into compact housings.
In narrow housings, the memory banks may be difficult to access below the power supply. In extreme cases, technically suitable modules are ruled out simply because of their height. You should check this in advance.
Mobile devices such as notebooks house smaller SO-DIMMs instead of the usual DIMM modules in computers. These memory components are located on the underside of the notebook behind a cover and are easily accessible after removing a screw. Netbooks and Chromebooks, on the other hand, are difficult candidates: Here it has to be decided from model to model whether the replacement overtaxes the technical skills.
