Hello,

If you directly plug your laptop to the power outlet and there is no sign of power indicator then probably the input power supply got fault. if there is indicator then the switch maybe error or if the laptop boot and cannot continue ..maybe memory and video card. first try to verify the power input of the laptop.

may this initial help,

It could be a bad battery, or a bad power plug which would not pass power to the battery. If possible, replace the battery with one that you know is fully charged. If that works then you will have to have either have the adapter checked or the plug itself may be loose and needs to be re-soldered. If it did not work then something else is loose and you should have it taken in for a complete exam.

Ideapad U260 won't turn on after battery replaced


Hi, can you remove the battery and plug with direct power

Tip

How to replace the CMOS battery in an Acer Aspire laptop.


General info
All laptops have a CMOS battery. The main purpose for the CMOS battery is to store the system time, date and BIOS settings even if the computer is turned off or the main battery dies. Individual Acer Aspire laptop models differ somewhat, but the general steps are the same when replacing a dead CMOS battery.

Before you start
1) Read through the owner's manual for your particular Acer Aspire laptop to determine what kind of CMOS battery you need.
2) Purchase the battery through Acer or a local or online computer parts dealer.
3) Turn the laptop off and unplug it. Also unplug any external hard drives, cameras, or other external devices.
4) Turn the laptop over (bottom facing up), then touch something metal to remove static charge.

Removal of the CMOS battery
Remove the Phillips screws that secure the motherboard cover (refer to your owner's manual if necessary), then release the cover from the clips on the bottom of the plastic casing. Lay the cover aside then locate the CMOS battery cable on the right side of the motherboard. Unplug the cable then remove the battery.

The battery should look something like this

slasher_x_2.gif
Plugging the new battery in
Plug the new CMOS battery cable into the motherboard. Slide the battery partially under the laptop casing (somewhere to hold it in place), then align the cover with the slots on the bottom of the laptop housing. Replace the screws then turn the laptop back over.

Finalizing
1) Turn the laptop on.
2)Enter your BIOS (usually by pressing the "Delete" key) before the operating system loads.
3) Follow the BIOS prompts or refer to your Acer Aspire owner's manual to reset your time, date and desired system settings.

Reason: Anytime the CMOS battery is unplugged for more than a few seconds your BIOS will be reset to the default manufacturer settings. If you make any changes to the BIOS that cause problems with your Acer Aspire, unplug the CMOS battery for 3 to 5 seconds to correct the problem.

The laptop can not be turned on though it is plugged in


Usually such old laptops show problems to turn on if the battery has a loose contact or if its completely blacked out. Looks like you have to change the battery and then keep the lap on charging mode for 2 hrs and then switch on the system and it will work. This is set as a default by some manufacturers to ensure that the lap works on backup on a sudden power failure. Please remove the battery, use a multimeter and check the voltage which has to be a minimum ranging from 7 V to 14.3 V and if its anything less than the same, you need to change the battery which will fix this issue. Good Luck

MY BATTERY WAS BLINKING, THEN IT WENT OUT.


Hi,

Try to remove the battery and connect your laptop directly to the power adapter. We need to rule out that there is nothing wrong with the power of your laptop. Now, if the laptop turns on with just the power adapter. turn it off and place the battery. Make sure that the battery is charged. Then before turning on the laptop remove the power adapter. If the laptop won't turn on then there is something wrong with your battery you need to replace it.

I changed my Cmos battery & my laptop would not start after tha


Without battery, BIOS just gets reset to default and should not effect boot. There is a possibility that you failed to reconnect something important when disassembling the unit.

What exactly happens when the unit turns on?

Cannot turn on


Ok - was there lightning recently? Does the laptop spin up, but no display? Doesn't it start up at all? Did you try it with the charger plugged in? Is there a battery you can change and try it with that?
If there is no display, try toggling te fn + f4 button, or the f(key with the little screen on it looks something like: |square|)

otherwise try using an external screen? Hope this solves your problem. If the laptop doesn't power up at all, even with a new battery/while plugged in, my best bet would be motherboard damage, in which case it needs to be replaced.
