Modernization and upgrade strategy
Transforming an old laptop into a modern work tool is possible with the right approach to upgrading. The most effective step is to replace your outdated mechanical hard drive with a modern solid state drive (SSD). This will give a tremendous increase in the speed of loading the system and launching applications. SSD installation - This is a mandatory stage for any modernization.
The second important step is to increase the amount of RAM. Although the model formally supports up to 8 GB, 4 GB is often enough for comfortable work in the browser and office programs. If you have 2 GB, upgrading to 4 or 8 GB will dramatically change the experience. Increase RAM will eliminate freezes when switching between tabs.
For enthusiasts, a processor upgrade is possible, since the PGA989 socket allows you to install more powerful mobile CPUs of the same generation. However, before replacing, you must ensure that the BIOS is compatible and that the cooling system is sufficiently efficient. Replacing the processor Requires soldering skills and caution.
βοΈ Lenovo B590 Upgrade Plan
Don't forget about replacing the thermal interface. Old paste often turns to stone, no longer dissipating heat. Using quality paste or thermal pads will significantly reduce temperatures under load. Thermal paste must be applied in a thin layer for maximum effectiveness.
β οΈ Attention! When replacing a processor, make sure that the cooling system can dissipate the heat of the new chip. Installing a powerful i7 in a system designed for an i3 can lead to instant overheating and shutdown.
Features of replacing the processor
3rd generation Intel Core series processors (Ivy Bridge) have different heat dissipation. Before purchasing a chip, check the TDP specifications of your motherboard. Also update your BIOS to the latest version before replacing to avoid compatibility errors.
Repair of the cooling system and thermal interface
