Hello friends, This is my first post in TECHSPOT, hope all are good. My exact problem is already present in this thread wwwDOTtechspotDOTcom/vb/topic93172DOThtml Wish the mods had kept it open for further discussion. Here is my version of the problem: My laptop is little more than 3 years old (Dell Inspiron e1505) I went to turn it on, and it would not start up. Instead, it would power on and the screen would say black. The fan would come on the power light would come on. Also, the number lock and scroll lock lights would blink, and the caps lock light was solid. I could hear the hard drive thinking about starting up. This would last about 30 seconds, and then it would power off. I read around the internet and found a solution, which was to "reseat the memory". I took the bottom access panel off the memory and took the chips out of the A and B slots. I then put them back in securely and made sure they were in. Still nothing happened, then it strike me that either if one of the memory cards had failed, but I was wrong, I took both cards out and inserted one card in slot A and left other open and started it started , means one RAM was good, then did the same with other card, inserted it in Slot A and started it too worked, Now my problem is I feel there might be something wrong with slot B. Usually this problem I encounter whenever I change the position of my laptop, for eg, If I do some cleaning on my laptop then this blinking of scroll ,caps lights and not starting problem occurs, the solution known to me was to leave the laptop unattended for about 1-2 hours and after 1-2 hours it automatically used to start, but now its headache for me to keep the laptop like this, since today morning I am trying after every half an hour but all I get is blinking, was not able to use my Night unlimited on BSNL ;-( Now after going through above thread on my PC, i have installed only one ram in my laptop and now it is working. My query is is there anyway to find out whether the slot B of ram is working or not. Some one please help me.
