There should be a battery inside your computer that powers the BIOS. Try replacing it and see what happens.

check your power supply and makes sure it is connected correctly, and make sure the power supply isnt a dud

Its better u plugged ur battery out...!\nEvery battery has LifeTimer..! when u left it plugged in, it will decrease its LifeCycle. \nTo ensure lasting ur battery, from time to time, try to charge it nearly 8hrs without turning on ur LapTop.!\nenjoy it ;)

are you powering up with your battery alone, or are you plugged into an outlet?\n\nhow old is your computer? is it worth spending money to fix it by going to a computer repair shop?  are your files very valuable?

Why did you take the battery somewhere to be charged if the laptop is not on but you have it plugged in you are charging the battery.  Check the metal connectors on the battery for corrosion, dirt, etc....  When you hit the power button does it make any noise(beep, humming?)?

VIRUS!!!!!!!!! or it could be a hardware problem, check your laptop's specs to see how much and what kind of RAM you can put in it.  RAM may not be the problem but if you put more in it, it won't harm it.  Maybe it's a power source issue, your battery might have problems.

Try powering up without the battery fitted if that is possible.\nI had a similar problem with a Toshiba. The battery was so dead that it effected the power to the on switch.

my brother's gateway has the same problem...after a while pc batteries run out of power...you drain a battery by using the laptop not plugged in until the computer goes to sleep because it has no power...

something is fried in your laptop, most likely the internal power module. the clear signs are, the lcd and the hard disk get no power.\ntherefore you have no other choice than getting your laptop to repair.

you may want to try plugging it into a different USB port. or If it is not powered by the port, make sure the outlet its plugged into is working

there is a green lamp on the AC adapter. does this lamp light wenn the AC adapter is connected to the outlet? is it still light when you push the ON-switch of the laptop?\nIf yes, you have a defective mainboard (more precise, a defective internal power module - this is the weak point of the most Dell laptops).\nbut - if the green lamp on the AC adapter dim when you push the ON-switch, there is most likely a short circuit on the mainboard.

Try plugging in your keyboard first and then turning your computer on. Where I work they have a very out of date computer and it did the same thing. We turned the power off and plugged in the keyboard. When we turned the computer on it worked.

It depends, If you are constantly in one place using your laptop, then there is no charge or discharge done. Keeping it always plugged in is one way, but to prolong it you should use a battery optimizer. Use a search engine to find "laptop battery optimizer" this will discharge the laptop to 0% power and then fully charge it very slow, thus allowing the battery to caliberate. Message me if you have a question.

1.) Turn it off\n2.) unplug the power cord and ever thing on the back\n3.) Press and hold the power button for 20-25 sec then let it go.\n4.) plug ever thing back into your computer\n5.) Pressthe power button and see if it comes on.\n\nif it dose not work call someone who know what they are doing.
