Whenyou connect the power adapter into the laptop, does the power LED lightup? If not then -
The battery adapter or the adapter's power lead or the laptop's powersocket could be faulty.
Check power adapter's DCplug that connects into the laptop power socket with a multi-meter, the voltageshould be slightly higher than the voltage that is printed on the label on thebottom of the adapter. If the voltage is zero or way below the voltage that isprinted on the label then the power adapter is faulty and needs to be replaced.
If the adapter is OK thenconnect it to the laptop and power it up, then look at the power/batterycharging LED light and wriggle the power plug in the laptop's powersocket. If the power/battery LED light flashes and in a certain position thisLED light stays firm, then the power socket is either faulty or it has a drysolder joint where it is connected to the motherboard.
This can be repaired but itrequires the laptop to be completely dismantled to get at this power socket andrepair. If you cannot DIY then I suggest you get a quote first.
hi shanur, i am happy to assist you,before reading my text its more better for you to see this video on the back of laptop you can find some screw remove it so that maximum part of laptop sheat wil be open in that you can able to find out cmos batter more ever in al laptop i wil be taped, romove the tape and take cmos batter and put new one. good luck
Try reseating the RAM modules first. The RAM may be faulty or reseating to make proper electrical connection. Get the RAM tested in another laptop or at your friendly computer shop.
Can you get into the BIOS configuration?
Did you power up the monitor first then the laptop? This method will divert the video information to the external video port first automatically.
If you don't get an image on the monitor and the hard drive doesn't appear to be spinning, then you could have a faulty motherboard.
I have seen this on several ACER Laptops. It is always the Motherboard. Contact Acer repairs and order a new motherboard. IT will likely be about $200ish dollars. Then follow one of the guides on the web for taking your laptop apart and replace the board.
Try removing the power cable and battery, while these are removed press and hold the power button on the laptop for 30 seconds. this is called a hard reset, what it does is drains any residual power in the laptop. if this does not work, that means there is an issue with the motherboard. to have it sent in would cost about $398, give or take.
Is it POSTing? Do parts make noise and then theres a Beep? The beep means it finished the Power On Self Test. Once it posts then it will show splash screen or black screen with it testing hard drives disk drives etc.. If no post is the led lit that says A/C is connected? before you attempt to turn on? If no post and good ac to rear connector then you probably need a new motherboard.
I guess I can assume that you have it plugged into the ac power, so you know its not a power problem.
We also know its not a problem with the power switch since the light turns on.
So that leaves, motherboard, cpu, and ram possible problems. Ram would unlikely cause such a hault. Even with no ram, I believe the computer would make horrible beeping noises.
So if its a problem with the motherboard or cpu, its pretty much trash, unless you want to waste the money on ebay or some place for another cpu to try to swap.
