Dell 1555 Studio laptop won't power up. After the power cord is plugged in, the LED light on the side blinks white once and orange four times. What could be causing it and how can it be remedi

What color(s) is (are) the blinking light? Is the blink a simple on/off or is there a pattern to the blinks (long/short)? Do any other lights come on and blink? (These could be on the keyboard or the battery health indicator LED.)

If the light that is blinking amber or orange indicates that the system has failed the Power On Self-Test (POST). If the blinking light is white, the system is in sleep mode. Try disconnecting the power adapter. Take out the battery and remove all external peripherals. Press and hold the power button for 20-30 seconds to discharge the system's capacitors. Try to restart the machine with only the battery and AC adapter. Did the behavior change?

You can remove memory and the hard drive to check if those are causing a POST failure. Reinstall one memory stick at a time if you have a pair or more. If you can get to the Dell splash screen, try pressing F12 to launch the diagnostics. (You may have to press the key repeatedly starting from a cold boot.)

If the blinking light is alternating orange and white, then you could have a problem with the motherboard, battery or AC charging system. Since you believe that the battery and adapter are OK, then the problem would likely be the motherboard has been damaged. The damage could be at the connection for the charger or somewhere else.

I hope this helps.

You've got an issue with your Memory or the Video Card.

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. Most times the problemis with the memory or Video Card. Count the Blinking Lights or Beeps and takenote of their pattern (1 Long or 1 Long followed by 2 Short).

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.Maybe your memory is bad or the memory slot is bad.Remove the Power Cord, Remove the battery, Remove the cover that houses the memory then remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.

Great story, but I feel your pain. There are so many times people think that just because they bought it new it works. Not true at all.

LOL, It means whoever sold you that Power Cord probably sold you one with the interchangeable end that can plug into any laptop. If it's not the interchangeable end type, they sold you one that is not compatible with your laptop. Get rid of it in a hurry before it burn out your motherboard. You my friend need to get on ebay and purchase a power cord designed specifically just for an Dell Inspiron 1525. All you need to search for on ebay is Dell Inspiron 1525 AC Adapter. They probably cost less than $10

Hello, Simon.

The most common reasons for power issues are the battery, power jack and power adapter/cord.

Power off and remove the battery. If the laptop powers on with just the adapter connected, your battery is faulty.

If you move/wiggle the power adapter at the point where it connects to the laptop, and the power goes off and on, the power jack is the problem.

The power jack is inside the laptop and either needs soldering or replacement. If a power jack problem, it should be addressed by someone knowledgeable.

If no change, the power adapter is probably faulty and needs replacement.

Hope this helps.

go to one of those computer stores they will tell you

First, check the RAM.. If possible replace it by a good one for testing or clean the pins of the old one using clean paper.
Second, its processor...
Third, maybe it is the inverter of your LCD display or the whole LCD. Test it using external monitor by plugging your data cable to it monitor port.

Try removing the battery , and the power cord, and making sure the laptop is off..

Then press and hold down the power button for one minute firm..

Then put the battery back in, then plug the ac cord back in, then try to turn it on..
