Re: my laptop won't turn on
Remove the battery and power cord for a few minutes then try again. if that doesnt work, remove the ram and put it back in. there is a good chance you friend something. do you have the power ratings of the aftermarket charger you tried? and did it turn on at all with the aftermarket one?

You need a genuine Dell charger not an aftermarket one. If the problem persists with a genuine Dell charger (and if the laptop is out of warranty, otherwise if it is still in warranty, send it back), the problem lies in a faulty voltage controller on the motherboard. Dismantling the laptop and putting a multimeter across the terminals that exit from the charging port will indicate if you are getting a voltage fluctuation through the charger. Aftermarket chargers especially those bought from the far east are very risky as they are often poorly built and badly insulated. Given the problems you describe, I'd be inclined to take it to a reputable repair shop to be on the safe side. NEVER attempt to dismantle the charger though!
Could be many things. Let start with a couple of easy ones.1) Unplug charger from computer and outlet, take battery out press power for at least 30 sec. Plug every thing back power on. 2) charger bad won't turn on or charge battery, try diferent charger if don' know how to use a voltmeter. 3) power jack loose or broken. 4) last and worst mother board circuits transitors etc... btw processor, video card or input devices fried. Buy new board from ebay. Don,t fix it. Not worth it. This is Only if laptop gives completely sign of not turning at all. No lights, no hardrive or no working or fan. No signal of life. If couple of lights do turn on it can be the ram or video card, play with ram a bit. Good luck.
Take out the battery and connect the charger. Then try to turn on the computer. If it works, there is no problem with your computer. After that insert the battery, plug in your adapter and try turning on once more. If it doesn't work, you need to get a new battery.
This is due to the laptop failing the "Post" process. This symptom typically leads to a point in time when the processor overheated, and is therefore dead. Or the RAM in the laptop is bad.
1. To test the RAM; start by pulling it out and then putting it back in: This will test for an "Un-Seated" stick of RAM.
2. If the laptop still doesn't boot, then you need to test the RAM further by trading it out with a known "working" stick of RAM or have a repair professional do this test for you.
3. If you put in a working stick, and the laptop still won't boot, then it is safe to say the procesor is toast.
If the laptop is only about 1-2 years old, it is worth replacing the processor. If it is older than that, I recommend buying a new laptop and an external enclosure for the drive in the current laptop. That will give you access to your files from the old laptop.
IS it a new Laptop. If yes what you can try is removing the battery and then switching it on.. Once its started just reseat the battery while its on power. You might have to try it 2-3 times if that doesnt help then your battery is broken..
I've seen this happen on several different cases. There could be one of two things that can be going on.
1. Your Charger is bad (but not completely bad). I mean that it took an inverted charge and every time you plug it in, instead it turns off your computer, or drains whatever power you have in it. It can rightfully explain the lowered usage of your battery.
- Sometimes taking a magnetized object (like a screwdriver) can be touched to the tip of the charger and it can reverse the polarity. WARNING!!!! UNPLUG THE CHARGER BEFORE DOING THIS!!! YOU MAY GET YOUR BRAINS FRIED IF YOU DON'T!!! I would say that maybe 60/40 chance it would work. Otherwise try another charger. Universal chargers can be bought at Compusa.com or Best Buy relatively cheap. As low as $35-45.
2. On the motherboard, there is the plug-in area where the charger goes. It might be experiencing a short. This can usually happen due to faulty wiring, or a fall, bump, hit, or crack to the computer.
On a side note. If your computer is over 1.5 years of age, the battery is going to start lasting less and less. Most Lithium-Ion batteries have a primary lifespan of 2-2.5 years. Some go out before, some go out after. It's all a bell-curve.
Take out the battery and only hook up the charger. If the laptop turns on then you know the battery is shorting out the motherboard. If the laptop doesn't turn on then you know that the charger is bad and you would need to buy a new one.
