SOURCE: 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...

SOURCE: Acer Extensa 5630 not booting

seems you have two problems
the ribbon cable on the lcd may be loose,
or need replacing ,
also check the pin in the dc jack if it moves at all or need to wiggle the ac adapter,it could be bad jack, but first make sure the ac adapter end is not bad, as the hole in the end gets bigger , it may not be connecting right

Okay, Here's the deal..... I recently had the same problems with my friends' Acer Extensa laptop and here's what I did to fix it. I narrowed the issue down to two culprits 1. Overheating, 2. Defective Motherboard. I have fixed the problem but I takes time, patience and some technical ability which may not be available to some. :( (Swapping out the motherboard MAY fix the problem but if the defect is in the manufacturing process then the problems could return). Here's how I fixed it... While in the process of disassembly I noticed a small electrolytic capacitor that had seemingly broken off and had become wedged between the frame (<ital>very lucky! this gave me the clue I was looking for!</ital>). This made me think that it had broken off the motherboard. I proceeded to disassemble the laptop and found the location of the missing capacitor (there are two located right next to each other on the board) and was able to re solder the capacitor back onto the motherboard (could it be a manufacturing processing defect thats causing these to break loose? ). Mine was broken off due to what looked like bad solder joints. Your capacitors could still be attached but have weak solder connections. Also while i had access to the motherboard, I used the opportunity to clean and re apply the heat sink compound to the CPU and thoroughly clean the fan vents. I then reassembled the laptop and EVERYTHING has been running fine now for the last 3 days. Total time was about 4hrs and it cost NOTHING to repair. GOOD LUCK :)

SOURCE: Acer extensa 5630ez won?t turn on.

Can you give a location of R138?
Is it on the easy side? E.q. the side of the motherboard wich is accessible by removing the bottom plate? I see Q24, located close to CPU. If possible, post a picture of R138, with some components visible.

Acer extensa 4620z whe i shutdown laptop it's shutdown but the screen power still remains on untill i hold the power button to off , please help me


It seems that your computer needs to have a reinstall of your original setup, because the driver that tells it to shut down is not cooperating. Hopefully you have your original dvd/cd.

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.

System cpu fan cycles on and off 2 or three times and no display when you turn it on. ?


try to turn off the laptop and remove the battery and the power cable. Then press and hold the power button for 5 secs. Then reinsert the power cable and battery on to your laptop.. Turn on the laptop, and if the cpu fan cycles on and off, that means there is problem with the fan and also the power supply of your laptop. Call Acer to replace the power supply to stabilize your laptop's electricity...

I turn on my laptop and it's dim. I press the FN


This is a Function of the laptop,you need to adjust your Power Settings. See the PC, does that to save Battery power, it will always be brighter, generally, on the Wall supply. You may need to set up a profile for both.
