    Tried everything. Disassembled and reseated everything but still the problem is on. When I switch the power on, the fan starts running for almost 3 seconds.

    I only can start the laptop early in the morning, when it has been off the whole night. It turns on and works perfect. But when I switch off and try to restart again, it fails. Maybe a motherboard problem?

Had the same problem, Removed the Hard Disk, Battery, and DVD combo drive. Reconnected the Hard Drive, Connected the power cable and booted up fine. Whilst computer still on put back the battery and DVD combo drive. Worked perfectly since.

Your problem is that a video cable has to be reseated in the connector:

Remove the battery, plug it in and and try to turn it on. If it turns on without the battery, the most probable cause is battery worn out.

The orange light shows the battery is charging. It will turn green when the battery is fully charged. The white light shows there is power entering the computer.
The usual problem with a computer when there is no response to pressing the power button is that the motherboard has failed requiring the replacement of the motherboard.
If the computer is still under warranty there should be a free motherboard replacement, if not, and you are able to do the replacement, you can find motherboards for sale on various websites. Be aware that motherboard replacement for laptops can be expensive if done by computer repair shops.

When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?

When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.

Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.Maybe your DC Power Jack which is where the power cord plugsinto the computer is bad. Take an ink pen and push the tip inside thejack and see if the little pin wiggles, if so the jack is bad. You'll have totake the laptop apart to fix it. Most times it is soldered onto themotherboard, so you will have to desolder the old and solder a new one.

Power light comes on but nothing happens


What type of laptop? What operating system?

Laptops don't boot for the following reasons: 1) Bad Power Cord. 2) Bad DC Power Jack where the power cord plugs into the laptop. 3) Static Charge Buildup. 4) Bad Motherboard.

The above 4 reasons are when you press the power button and absolutely nothing happens. You hear no fans running, no disk drive running, no one time clicking sound on the CD Drive and No light for a second or two when the CD drives click. In the case of a motherboard issue sometimes you will hear beep sounds or see blinking lights. Those beep sounds and blinking lights tells the technician what is going on with your motherboard and why it will not boot. If you see the blinking lights or hear beeps count them.

So you have a power light which means your power cord and dc power jack is good. So lets see if you have a static charge buildup.

Remove the Power Cord and the Battery from the laptop, then Press and Hold the Power Button for 30 seconds. After 30 seconds put the power cord back into the laptop, but leave the battery out. Press the power button to see if it boots. If it does you had a Static Charge Buildup and it's ok to put your battery back in. If it does not you more than likely have an issue with your motherboard.

Remove the main battery and the power supply, allow several minutes to get rid of any residual charge, now plug the power supply adapter back in and press power "leave battery out" is there any change? if not! remove power supply, now! press and hold power for 60 seconds to reset the laptop. Next install main battery back in and the power supply adapter, power up! if no change, the motherboard is the problem.

My Acer aspire 4935 is not recognizing the AC adapter. When ever I shutdown the system and connects the AC adapter, it works and the charging LED lights up. Once I press the power button to boot the...


Problem description:The battery charges only when the laptop turned off. The battery charge LED lights up as normal and the battery gets charged to 100% while the laptop is off.
When the laptop is turned on, the battery charge LED goes off even if the adapter is still plugged in.
Possible cause:1. AC power adapter failure.
2. Battery failure.
3. Broken/loose power jack.
4. Motherboard failure.
Possible troubleshooting steps and repair solution:1. This problem could be related to a faulty AC power adapter. It's possible that the AC adapter doesn't provide enough power when plugged into the laptop. To find out if this is your problem, you'll have to test the laptop with another working adapter.Replace the adapter if needed.

2. There is a slight chance that you have bad battery. Test the laptop with a know good battery and replace the faulty one if needed.

3. The battery charge problem could be related to the power jack. Maybe the jack is broken or not making good contact with the motherboard. It is necessary to remove the motherboard and take a closer look at the power jack. Resolder or replace the jack if needed.

4. If the power jack is in a good working shape and new power adapter with battery do not fix the problem, most likely you have a faulty motherboard. Replace the motherboard if needed.

Laptop won't switch on although blue power light on is showing power is getting to the machine


Check the power adaptor led is not flashing. Flashing Adaptor LED indicates fault with laptop charging circuit / powerboard

If it will not boot on battery, and you know the adaptor to be good, the issue lies with the motherboard.
Sometimes, removing the battery, and unplugging, pressing the power button and holding it for 30 secs, replacing the adaptor only will allow it to boot up, but this will only work if the motherboard is not damaged r the CPU fan has not failed.

You might try to remove and reseat the battery. Jiggle the plug for your charger just to make sure that it can deliver charge to your computer.

You may be needing a new battery for your laptop, especially if the laptop seemed to require more frequent charging.

Look for guidance on your manufacturer's web site about care and charging of your laptop's battery.

10 seconds shows that one component from laptop's motherboard is defect. Try to remove RAM memory, harddisk and dvd (If available) and put them back one by one to see which component is defect.
