Question about Acer Extensa 5420-5687 Notebook

1 Answer

My Acer Extensa 5420 will not power on. Battery light will illuminate when plugged in but ince you hit the power button the laptop will start to power up for about 20-30 seconds, you can hear the cd/dvd drive and such but nothing on the screen. It will back down and that is it. Maybe battery? RAM? Really not sure. Worked fine before this problem. Thanks for any help.

    The laptop will only power up for about 20 seconds and the only led's i have is the battery led and briefly the power button. Nothing appears on the screen at all.

First open back cover of lapltop then reattach both battery and RAM memory.
Then check.
when you power up the computer check num lock led if it is on and off when you press num lock key then your ram is working fine then you need to change screen resoluion.
For that when you power up the computer press F8 key if you are able to see safe mdoe and other menu then enter in "enable vga mode" then go to display property and change screen resolution to 1024*768 then apply.
But if num lock led is constant then you need to change ram.
Let me know if you need further assistance.
Thanks for using FixYa.

Acer extensa 5420 bios


Clean out the cooling fan/vents, etc. and try again. If the fan isn't turning, it won't boot up.
If that doesn't work, you may need to disconnect the power supply and battery and then hold down the power button for 30-60 seconds. This will discharge stored energy from your laptop. I'm not sure of the specifics, but this happens to mine every 12-18 months or so. Once you've done that, reconnect the charger and battery and try to power up again. It should work now.
If these steps don't fix it, you have serious problems.

Acer Extensa 5235 wil not power on


The solution to your problem lies in one of the following three areas:

1.) Your charger is faulty and is therefore not able to pass power to your laptops battery.

2.) The charging connector on the laptop has come loose from the contacts. Therefore a bad connection.

3.) Your battery is faulty.

I think possibility 2 is the most likely, although you will have to test possibility 3 by removing the battery and plugging in your charger and seeing if the laptop powers on.If it does power on then that rules out possibility 1 and 2 leaving a faulty battery.

Laptop wont start.


Remove the battery and unplug the power cord for 5 minutes, put in the either the battery or the powercord and power on.

if it doesn't power on, make sure the charging light is lit on the front of the laptop when the power adapter is inserted and plugged in properly.

light blinking when you power on means battery low / no power.

If the problem doesn't go away you need to contact acer for warranty service if you are outside warranty contact a local repairer.

Will not start on battery or plug-in to wall outlet - when holding down the power on button to start - nothing happens


Take out the hard drive and dvd drive and also make sure the battery is out. Plug in the AC Adapter and then see if the laptop turns on. If it still doesn't turn on then that means the motherboard is bad.

Acer Extensa 5420 won't turn on, not a power/battery problem.


Just for the heck of it, try blowing out the cooling fan with some compressed air. If you have never cleaned it and the fan stops turning, the computer will go into a safe mode and not start up.
Ther should be a vent somewhere on the side of the laptop that vents hot air cooling the CPU. That is where you need to blow it out.
Hope it helps- just a longshot...
