Acer 4420 shut down, will not restart

I have only had my laptop for a few months and today, out of nowhere, the computer shut down while connected to the wall outlet and will not boot. the power light flashes when i press the power on button, the system grinds once, then the power light goes off again.

the unit has been running hot lately, so i was afraid it might have overheated. any thoughts?

    first let it sit for abit till it is cool... then attempt to boot it

    second you may have to disassemble it to get to the fan(s) to clean out the dust and dirt that has collect there as it does sound like thermal issues.

    third remove the battery and attempt to boot up

    forth remove the wall charger and attempt to boot up with just the battery



    Let me know what happens

Allow heat to dissipate.
Clean vents with air compressed (on power off only)
Use fan support for laptop if you use CPU intensive application in hot environment or if air circulation is not optimal (on soft support, on your knees etc)

Acer extensa 4420 shuts down right after you push power button


sounds like it doesn't have enough power, is it completely charged? you may want to make sure you're getting power from the charger itself.

Acer Extensa 4420 overheating


The laptop must be dismantled to access the motherboard, buy a can of compressed air attach straw. Now remove fan and the heatsink, blow out all open ports and fins on the heatsink and fan, next! remove thermal grease from the processor and heatsink with rubbing alcohol and a paper towel, now! apply fresh thermal grease to the processor and heatsink, "small thin layer evenly spread" now assemble, "solves most heat related issues"

My acer extensa 4420-5963 gets really hot and shuts down. also, my battery seems to lose and gain charge within a few minutes. And norton's report says the laptop is running on low memory. help! please


It could all be down to the heat problem.

Check the fan housing, is it clear of dust. If not there is usually lies the problem.

When using the latop, ensure its on a flat surface so the air can circulate around the vents and fans.

"logging off" ... it never ends. now what?


From your start menu, choose computer, at the top of that window hit system properties, on the left hit system protection, It should be open to the system retore page, Hit the system restore button. What you want is to restore to the last day your computer shut down right. For me that was just before the last windows update on 5/7/2009 when my computer as well started not shutting down. The system restore doesn't erase any of your files it just restores the system files and drivers back to the date you specify. Worked for me!

I have the same problem my acer extensa 4420


I had a similar problem with my Acer Extensa 4420. After reviewing all the recommended solutions, I decided to open the case to see if I could see a disconnected cable or other easy explanation.

However, when I pulled the heatsink off the CPU and found that the heatsink compound had almost completely dried out. I cleaned the heatsink and applied new compound, then reinstalled the heatsink and put the computer back together.

It works great. Interestingly, this is the same problem that plagued the XBox 360 and the "red rings of death" failure. Just an option that is easier than pulling the entire case apart.
