My acer 4620 laptop is not working no power on and not charging nothing happens how to cheak by multimeter give full solution how can i cheak power suplly in motherboard

Try this one. If this won't work check out the other videos on the same page.

Try the following, one at a time.

- Remove battery then connect power cord, then power on
- Remove the memory modules then power on
- Remove the other optical drives, then power on
- Remove other components, then power on.

This process is to illiminate the faulty component. It is possible that one component is faulty and is causing shortage that's why your laptop won't power.

If this doesn't work then you need to remove the internal components like hdd.

Hope it helps.

IT MAY BE THE COMPLAINT OF OVER CHARGING OF THE BATTERY.SO TRY TO CHANGE THE BATTERY.

Try turning off your Acer wireless control and use "Wireless Zero Configuration"

First of all try to run Laptop without the battery,if it works fine then your Adapter is OK. Second make sure the battery is fitted well. Third try using it with some other Laptop if it runs OK there then probably it's your Motherboard Problem otherwise you need to change the battery. Fourth battery's average lifespan is 1-2 yrs after that it gradually starts decreasing,if it's that old then again might be a battery problem. Fifth Battery oftens loose it's charge percentage due to overheating. Try all the steps and it will help.

The battery is about to go. You can buy one at ebay that's more powerful.
