Here below is possible cause and troubleshooting steps of laptop that can power on, hope it may help:

Possible causes:
1. AC adapter failure.
2. Power jack failure.
3. Motherboard failure.

Possible troubleshooting steps and repair solution:
1. Test the AC adapter with a digital multimeter. It's possible that you have a failed AC adapter. If you don't have a multimeter, test your laptop with another known good AC adapter.
2. It's possible that power jack (socket where you plug the AC adapter) is broken. Remove the motherboard and take a closer look at the power jack. In some cases you can fix the jack by resoldering it on the motherboard. In other cases you have to replace the jack with a new one.
Using a multimeter, test if the power goes to the motherboard through the jack.

3. If replacing the AC power adapter and jack on the motherboard doesn't help, most likely you have a bad motherboard. Replace the motherboard.

Laptop hang issues can be a frustrating issue for the user and a tedious problem for a technician.


The variety of causes for this event are staggering, but many can be diagnosed in a few simple steps.


Peripheral Issues


USB drives, inserted before boot, will cause a hang.

Remove all such devices and media (such as CDs and floppy disks) before booting your laptop.


Software Causes


Press "F8" at boot and press "Last Known Good Configuration" to take your laptop to a previous working boot. Starting your laptop in "Safe Mode" by pressing "F8" at boot will help

you check for software causes for a hanging laptop.


By turning off unnecessary processes, this mode allows you to run anti-spyware and antivirus software to clear malware that hinders performance.

Perform a check disk by right-clicking on your "C Drive" found in "My Computer."


At the "Properties" link, press the "Tools" tab to schedule error checking.

Reboot your laptop and let it perform this check.


Hardware Causes


Verify that your RAM is seated correctly by removing it carefully from under its access door on the bottom of your laptop and reinserting it.

Do not touch its gold contact points, as this may damage the memory.


Download the hard drive manufacturer's diagnostic software to test the integrity of the hard disk.

If you have access, run a professional hardware diagnostic suite to check the motherboard and CPU.


Boot with the battery removed to verify that there is not an issue with power conflicts.


Final Considerations


Checking the "Event Viewer from Administrative Tools" located in "Control Panel" (XP only) can also shed light on potential causes.


Performing a repair installation of Windows can address missing files, registry errors and corrupted system files without damaging your data.


This process requires your original Windows disks but is often quite useful.


Press windows button and in the search type msconfig go to startup tab and uncheck those you dont want to start.


scroll to the bottom toolbar bottom of screen right click you can select task manager applications also processes you will see whats running on your computer and ticking over you might have a virus

Freezing


A computer/notebook/laptop can freeze due to a lot of reasons. Here are few noteworthy ones. Check them and see if they help, if not then post a little detail of when it freezes more etc:

a) Antivirus programs have a great tendency of eating up memory quite quickly. So, get a lightweight antivirus program like Microsoft Security Essentials or Avast etc.

b) If you have a low RAM then it is recommended that you run very few applications at the background. Avoid running any unnecessary applications.

c) If you have a desktop set with lots of transitions and effects it can cause huge RAM and often results in freezing of system.

d) Your O/S could be a problem too. If the above things doesn't help try resetting/re-installing the O/S and hopefully it shall help you a lot.

e) Check your system for any viral activities. You can perform an online scan using many free online scanners like Trend Micro etc.

Probably the model number of your Acer Aspire 3620 is already discontinued or placed into their archive files. Also, possibility that such model was produced in limited quantity & distributed only to a certain location like in the Philippines. I suggest to email them for your concern thru service@acer.com.ph, for their customer service & support. best regards
