If you have a laptop, there are no documents for it, but it is necessary to determine its model - do not despair. There are at least four easy ways to find out your laptop model and configuration.
It is necessary
Access to the Internet
Instructions
Step 1
First, take a look at the BIOS. On computers, they get there by pressing the delete key at boot time. But on laptops, it is often absent, and it is replaced by buttons from the F row. Depending on the model, this can be F1 and F12. In the BIOS, an experienced user (or someone who knows English well) will find all the information he is interested in.
Step 2
If the user is still not experienced, then a simpler path can be taken. Search online and download the small program Everest Ultimate Edition. After installation and launch, it will show you comprehensive information about the system. Even the one you didn't know about.
Step 3
However, these methods only work if the laptop is in working order. If not, then look for a warranty or serial number sticker on the bottom of the case (sometimes on the back). The model is written after the word model. But such a sticker can either be torn off, or (if the laptop is old) all the numbers on it are erased. Then inspect the battery - the stickers on it last longer. Although the model is indicated on all.
Step 4
If you still haven't found the stickers, you will have to switch to "manual" mode. Fill in the search engine "laptops + manufacturer's name (the marking on the case should have remained in any case)" and compare with the pictures. Not so fast, but not as long as it seems.
