Question about Dell Inspiron I1545 Laptop PC Intel Pentium T4400 22GHz 156" Widescreen Display 3GB DDR2 2 (884116031888) PC Notebook

1 Answer

I have an Inspiron 1545 laptop and it's just over one year old. The screen would flicker lightly around the edges, and then it would go black. In a bright room, I could see what was on the screen. If I power off the laptop and then turn it on again, the screen works for a few seconds up to a few minutes, and then it goes black again. I can hook up an external monitor to the laptop and it will display on the external monitor without any problems. It will display everything and play videos just fine. (I also have a 4 year old Inspiron 1300 laptop which has the same problem - so I am willing to try to fix that older one because it's not any loss if I destroy the computer). I've read that it could be a LCD inverter, or a backlight (both of which are cheap enough on eBay). How do I go about figuring out how to replace these parts, and how to get into the computer?

You need to replace both the parts here... The backlight is the main problem... But its advisable if you can replace the LCD inverter as well.. Replace them.. Since the display is working on the external monitor the problem will be fixed...

When I power on my Dell Inspiron 1545, it will say Windows Starting and then goes black. The power light will still be on but I have a totally black screen. Any suggestions?

Can you boot to Safe Mode. If you can, there is probably an issue with the graphics chip driver. If not, this could be a corrupted system file. Also try to boot to an extarnal monitor, eliminate the possibility of it being a screen issue

Dell Inspiron 1545 Booting Problem [Black Screen].

Insert the original Windows CD-ROM into the DVD-drive, and see if the computer will "boot" from that disk. If so, then it could be your 'C:' drive which is having the problem, and thus not "booting" your computer from it.

Turn power on and nothing but a black screen dell 1545, any ideas. Is there a reset button?

If it turns on and makes all the normal sounds, hold the screen up to a light and move it around. If you see a very dim picture then your inverter has failed. This can be fixed.
You can also plug an external monitor into the laptop to make sure that your graphics chip hasn't let go.

The screen on my dell inspiron 1545 64 bit windows vista is darker on one side than the other and sometimes flickers and progressively gets darker, could it be a driver? or something that i can fix online...

The CCFL [cold cathode Fluorescent] bulb is dying. Manufacturers use these thin 'tube' style lights at the edges of your display for laptops and LCD monitors & TVs. Don't let it go too long or you will possibly destroy the inverter that provides the power to light the bulb.

Dell Inspirion Laptop Screen Randomly Flickers, Then Blacks Out

not to get to concerned just yet, a few tips, when you press on the top of the laptop case by the screen area in the back of the laptop do you notice the screen flickering off? and when you let go dose it come back on? if so this can be a faulty wire or bad inverter, they are actually both very simple to fix and relatively cheap fixes.
