I have a slightly older laptop that works slowly too.
Therefore I wanted to ask if it is enough to install a ssd so that it works faster again?
Compared to a HDD you notice with a SSD in any case, a significant difference in speed, which is noticeable, for example, especially at boot times or when running programs. More RAM is also useful in some cases. 4 GB should be at least installed, at best 8 GB. It still matters what kind of CPU you have, but most likely a change will not be possible either way.
Yes, an SSD helps a lot. Already made a 10-year-old laptop afloat. The CPU also has an impact, but not so serious if you only have office and a bit of multimedia. Of course, that does not improve performance in games or so, or only to a very small degree.
I have an old HP 2530p with an old L9400 2 x 1.83 GHz Intel CPU and 4 GB DDR2 RAM.
Have had a 500HDD and swapped for a 120GB SSD.
The difference is OUTSTANDING!
Both while booting, while surfing and in the office. It is worth 100%.
In addition, the battery lasts longer and the PC is quieter.
