Laptop screen turns OFF at normal brightness level

HVipul · 09-26-2007, 02:53 PM

I have a DELL Inspiron E1505 I bought last April. Since last week, the laptop screen turns off a few seconds after it boots or resumes. I did some diagnosis and found it to be related to LCD brightness level.

If I start the laptop without the power cord connected, the laptop screen stays on. If I increase the brightness level, the screen makes a hissing sound and turns off in few seconds.

If I start the laptop with power cord connected, the screen makes a hissing sound and turns off in a few seconds. If I manage to reduce the LCD brightness during this time, the screen stays on.

Anyone have any idea how can I go about fixing this problem?

Thanks in advance.

It sounds like you got it with a faulty inverter board. Your best bet since your laptop is probably still covered by warranty is to contact Dell support and have them fix it.

THe laptop is no longer under warranty. What are my other options? Thanks a lot for the reply.

You said you bought it last April - the warranty is 1 year so wouldn't it be covered?

Sorry, I should have been more clear. I bought it in April 2006. I only had one year warranty on it. I tried Dell support, but it says they will charge me $40 to even talk on phone and plus $159 minimum for repairs and usually more than that for LCD repairs.

If that is the case would would save a lot of money by taking it to a local shop. They should be able to order the part and fix it for less than Dell. I would recommend doing that.
