ok first of all check your adapter weather its working or not. For this you can use digital or analog A/C D/C meter. If the adater is working fine the next thing is your main battery pack of laptop. Usually all manufactures only give 1 year warranty for battery pack and in some casses battery pack did not work properly due to extensive charging . If it is in warranty then go to your dealer from where you buy the laptop. The third and final diagnoses for this problem is the system board of your laptop. Because sometimes due tp spike of electricity cause damage to the system board of laptop and make it unabel to charge the battery or even start with the adapter pluged in. \n\nSo if your system board is damaged and its not under warranty then I suggest to get a new one dude.

You'll need to take the laptop apart and find the CMOS battery. It looks like a watch battery attached to your laptops motherboard. Take it out for 45 seconds, then put it back in. This sets your BIOS back to defaults and also removes your password. I wouldn't suggest doing this if you've never been inside a laptop.

Yes you could have burnt it out but not because you plug it into the wall socket and use the battery at the same time.  It may just be that there was a power surge/spike.  Get it checked out by a professional.  If you could see melted plastic then definitely something is wrong.\n\nGet a quote for a repair and see is it worth getting a new one.  These things are repairable.  \n\nHave you tried plugging it into the wall socket and boot the laptop up?   What happens?  Any signs?\n\nBattery Wizard

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.

Contact dell and tell them you want a new battery. dont leave it any longer, cos after the 1st year they dont want to know about the battery.\n\nTrust me your battery is fubar, its happened to me several times.

If its the power adapter, why not replace it.  theres universal ones out there at most popular stores, and if you search the internet and hit the auction sites you should be able to find it relatively inexpensively.\n\nAs far as fixing the power adapter, Id try either doing a google search for fixing circuits, OR go down to the local bookstore and/or library and pick up a book that way.\n\nI dont know if Id be so bold as to try experimenting with the power adapter if I wasnt knowledgeable since a power fluctuation could do some serious damage throughout the laptop.\nThats up to you though

I would call dell tech support up and let them know the battery is a dud.  To keep the battery lasting longer fully charge it then let it drain 2 or 3 times right off the bat then fully change it and drain it once a week do not leave the power cord in the computer when you don't need it.  If you do this constently it will kill the battery.

your LCD screen on the laptop is damaged. Send it bad to the HP manufacture as a RMA through their website, they should repair it if its still inthe warrenty

2 possible reasons\n\na) If you are lucky: your graphic card drivers are messed up. All you need to do is reinstall your graphic card ( using its recovery cd or downloading it from its brand's website )\n\nb) If you are not lucky: your screen is dead. Leave your laptop off for some minutes and turn it back on. If it still is turned black you best take it to the first laptop shop.

Remove the battery and try just ac. I've had some laptops stop working because the battery had no charge. If that doesn't work, get it serviced.

Maybe your battery has a problem? what I suggest is for you to take out your battery and plug your laptop without the battery. If your laptop works fine, then its a battery problem. If the problem still exist, put back your battery and  change your charger. Did you drop your charger before? there may be some loose connections inside.

I'd try plugging it into the computer and see if that does anything, other than that, I guess you just have to let the battery die...

What is the exact problem you are having, maybe it is a simple driver that you need to re-install a driver. What type/model of Laptop do you have? What is the exact problem that you are having? What have you done so far or what jobs have being down to your laptop? I am willing to help you out on your problem with your laptop, just explain it a bit on the issue you are having?

On a laptop, it shouldn't affect the computer, provided your battery is in good working order.  If your laptop's power supply failed, your batteries should kick in until AC power is restored.  If you think it's your power supply, try to get another one to see if it happens with that one.  If that's not the case, then it may be an internal issue (overheating, for example).\n\nOn a desktop, though, the power supply might be a cause, but then again, viruses, a bad motherboard, or overheating could also be causing your computer to reboot spontaneously.  You'd have to take more notes when it happens - does it happen when you do a particular thing (maybe a virus) or after a certain period of time (maybe a virus or a heating issue), or is it completely random (power supply may be working intermittently)?  And then, after your computer shuts down, does it come back up immediately or does it take a few minutes to start again (maybe a heating issue)?  I would check for viruses first before getting into the case.  If I went into the case, get some compressed air and blow out all the dust, and then see if all your fans are working properly.  And if that doesn't help, try another power supply if you can.

It depends what exactly is broken. If the backlight is broken, it can be replaced, or if the power inverter is bust, that can be replaced too.\nIf the screen itself is cracked, you can only replace it...\nHeres a site that may help:\nhttp://www.screentekinc.com/\nCheck your video card is working correctly by hooking an external monitor first, as this may be the problem
