Hi , i jave aproblme with my dell inspirion 1564 , the charger is plugged in but no charging , and the led of chargining is off

You either need to replace the carger or the bit that you plug the charger into.

You would have to undo the screen cover to get access to the web cam.

The charger is not charging the battery. It could be the battery is dead or the laptop motherboard has a problem that wont allow it charge the battery OR it is a DELL and you are not using a DELL factory charger

Sounds like the battery is dying.

try system restore

it could be a couple things: Are you using the standard 90 Watt ac adapter, or the Travel auto/Air adapter. The travel adapter is only 65 watts can will charge the battery
If using the standard ac adapter, see if you can try another Dell D series adapter and see if you get the same error.
If same with another adapter, the issue is the charging circuit. If another adapter works, then replace the adapter.
If the charging circuit is bad, it will be the chargerboard or if intergrated, the motherboard

This can be fixed by reinstalling the web cam or your laptop doesn't supports the web cam.

it might be due to problem with ram or your display adapter in the both the cases you have to open the case,

plug is bad or the battery is bad one of these 2 things need to be replaced if you have a car charger try that it will let you know if your battery or charger needs to be replaced

car charger will start chargin battery

Also, check to make sure that you have a good connection between the laptop and the charging cable at the power port on the rear of the laptop. We have an Inspirion 6000 with this problem and we've discovered if you pull the power cord out very slightly and lift it upwards, the charging icon appears in the system tray. Appears to be a fractured connection inside the laptop at the power port. Changing chargers does not make any difference.
