Its not your display.... your A/C adapter is losing connection.

your brightnees is set to LOW on battery, and HIGH on A/C... which is why you think it flickers.. it is just losing and gaining A/C connection.. so it goes bright, then dark, then bright, then dark.. or A/C, then battery, then A/C, then battery... you understand?

try holding the A/C cord, where it is plugged into the back of the laptop, in one spot.... then move it to another spot and hold it there... does the problem stop? Then your A/C cord has a bad connection to your motherboard, which means you need a new motherboard.

good luck, if you thought this was a good solution, please vote.

Dell Inspiron 4100 flickering off and on Makes it extremily hard to work with . How can I tell whether it is the display or something else?


What happens when you hook it up to a external monitor? If it works fine with a external monitor, then your laptop monitor is going bad. If it does it with an external monitor, then its more than likely an issue with your laptops video adapter.

Dell inspiron 1520 won't turn on.


Remove the battery from its compartment on the side of your Dell Inspiron laptop computer.


Remove the power adapter from its plug on the side of the Dell Inspiron (if your laptop is currently plugged into a wall outlet).


Press down and hold the "Power" button on the laptop for one to two minutes. This will dispel the excess electrical current that is built up inside the laptop.


Put the battery back inside the compartment of your Dell Inspiron.


Plug your power adapter back into the side of the Dell Inspiron. Press "Power." Your laptop computer will now turn on.


hope this helps

What does it mean when lights flicker on dell inspiron 1100


Most of the time it means your battery is dead... try to unplug the battery on the bottom of the laptop and plug in the power supply. Try to turn on the computer. If it comes on, then you have a bad battery. Check eBay for a new one.

If it comes on but still flickers with the AC adapter plugged in, then you have a bad battery and it needs to be replaced.

My inspiron 6000's power flickers on and off intermittently, switching between A/C & battery power. I've replaced the power cord. Any other ideas?


Try removing batt and use ac adapter alone. Check if laptop works fine also check if LED flickers still.

Try removing ac adapter and use battery alone and check if batt flickers as well.

If flickering only happens when both are connected or vice versa try this first. Update the BIOS for your laptop. Download the BIOS update from http;//support.dell.com

Battey not charging, red light flshing


Check the power adapter with a multi-meter, the voltage of the power plug that plugs into the power socket on the laptop should be slight higher than the voltage that is printed on the label on the adapter.
If it is faulty, there are replacement power supplies available on the Internet or at your friendly computer shop.
If the adapter is OK then the power socket on the laptop is faulty or this socket has a dry solder joint connection on the motherboard.
You can test this by wriggling the power plug when it is connected to the laptop, if the charge LED flickers and if you hold this plug in a certain position the charge LED stays on without flickering, then the power socket is faulty.
This can be repaired, but requires the laptop to be completely
disassembled. I suggest you get a quote first.

Dell laptop screen goes blank when ac adapter plugged in


I believe I have found the problem with the 1525 that I am currently working on which has the same problem that you describe. Ultimately I think it's a problem with the inverter in the LCD. When the laptop is powered by battery the brightness is lower than full. When I plug in the power adapter the brightness goes to "full" and I hear a faint sizzle and the LCD's backlight goes off. Same as if you hold the Fn key and press the up arrow to brighten it, it will do the same thing when you reach near the full brightness. So for now I have fixed this problem by going in the Power Options and clicked on Adjust the display brightness on the left. Slide the slider to the left on the "plugged in" part and now when you plug it in it shouldn't make it go blank. I do want to note that I hear a faint buzz coming from the LCD when I plug it in. That must mean the inverter is faulty. WAY TO GO DELL!!!!!!
