I have Minecraft on a Toshiba Satellite. It is less than a year old & has Windows 8. I downloaded Minecraft the other day & it is lagging HORRIBLY! I tried setting the settings to the lowest they could go, & it's still lagging!
Minecraft is Lagging Badly?
Have you made sure to update your java to the latest version and correct one for your operating system? Try updating your java to a more recent one for your operating system, then update your drivers for your display adapter.
Like the above yes I would recommend that yo check if your software is up to date but it just may be that your computer is not up to the task of running it.
I looked up the computer and it seems that it has integrated graphics as well as only 4Gb or Ram
Not sure if its the right model but in that case you would not be able to run it
Hmm. I have the same laptop and Minecraft runs just fine. Make sure you have 64 bit Java (assuming you have 64 bit Windows) and I recommend you install Optifine. Optifine lets you set the video settings even lower than the lowest on vanilla Minecraft. Also, make sure you have the latest version of Java (right now I believe it is Java 7 update 55). If you have everything installed and updated correctly, the reason for lagging might be a computer virus. As a last resort you could allocate more RAM to Minecraft (Java) in your profile settings in the Minecraft launcher. Hope this info helped!
Here is a link to check your Java version: https://www.java.com/...applet.jsp

P.S. Installing Optifine is easy, just run the Executable Java file that you download from Optifine's download page.
