Simple settings such as muted speakers or inactive speakers could be the reason why there is no sound.

Speaker could not be set to default audio for the device which would not allow the integrated speakers to function as the primary source of audio.

Speaker components themselves could be damaged or become disconnected.

Some easy solutions you can try are:

1. Restart your laptop
2. Try to clean the keyboard
3. Check if it's a hardware issue
4. Check your keyboard drivers and settings
5. Make sure you have the right keyboard layout

When using the laptop, it gets excessively hot to the touch and seems to lag

Having a functioning cooling system is vital to allow a computer to work. The fans in the component may be clogged with dust and dirt which can cause them to stop spinning as they should.

Being in a room that is too hot or lacks good ventilation could affect the performance of the device and make it easier to heat up.

Having too many programs and applications running at the same time could severely affect the performance of the device and cause it to be overworked.

Tips:

1. Make sure the laptop air pathways are clean
2. Try to prevent the laptop from getting hit by sunlight or performing in a hot environment such as a space with poor ventilation

In most cases, a faulty charger is the main factor as to why the battery does not charge. If this is the case, replacing the charger with a new one will do the trick.

The battery component itself could be damaged as well. If this is the case, a replacement battery should be installed.

Tips:

1. Buy a new charger 
2. Clean the power port
3. Replace battery

Specific drivers could be outdated and in need of either updates or replacement with a newer driver.

The laptop could be experiencing overheating, which would cause the component to shut down until it is cooled off again.

Tips:

1. Don't use the laptop while it is charging as this may cause it to overheat
2. The last resort would be to buy a new batter
