Hello,
I am a owner of cell inspiron N5110,early 2011 laptop. I had a battery which ran out of life and was using it on the ac adapter.Now the laptop has a black screen whenever it is switched on. The adapter is working fine as I have tried it on other Dell laptops. I have tried switching on the laptop by removing the battery as well as changing the power source,having no change. I tried to tackle the static problem I found on other discussions in the forum by removing the battery and the adapter and holding the start button for 10-20 seconds. When the start button is pressed the computer has three hardware buttons which light up and then go out on their own. I had a defective CMOS battery which beeped 5 times in a triplet on every boot, this has been missing as well as there is no evidence pointing to windows start up such as windows start up sounds or anything, suggesting it is not a screen issue. I had the same issue a day back but the laptop eventually recovered on its own without a big time gap. What seems to be the problem?
Thank you
