Hi there, can you tell me what the towel/blanket method is and where you saw this as a fix? Is this similar to what some people were doing when they were trying to heat up their Xbox 360s to try get the system to fix itself from the Red Error light? If so... I do not recommend doing this on your system, especially since you're still in warranty.
Disassembly isn't too bad and I can link the Service Manual w/ steps, but before we I that or you take it apart, can you try running Diagnostics on the system? You can enter diagnostics by pressing F12 at start up (at the Dell screen) and then selecting Run Diagnostics. I would run the full set.
It sounds like this could be related to a bad board, bad power adapter, or maybe a battery, but let's run the diagnostics first and see if it shows anything.
hello brad. sorry for my late response. I cannot get to the dell screen, thats the problem. during the process the whole screen is black. during my earlier tries the dell screen would come up, but it hasnt come up since the first or second day. the only way to get to the dell screen was to use the blanket method, but the laptop only actually turned on once and it was slower than normal and the audio wasnt working properly. the keyboard also wasnt working.
the towel/blanket method is the same thing as the xbox 360 method. I've seen it on youtube videos and almost every thread ive looked at in attempt to solve this problem. for other people, it only takes 10-20 minutes to get their laptop heated up. some say to turn it on ten seconds after it's heated and some people say let it cool down completely. the one time it worked for me was when I had it in the blanket for 2-3 hours because my laptop hasnt been heating up as fast and I had to do it while it was still hot. if I let it cool down I wont even be able to reach the dell screen.
I was hoping the method would work because I have very important things on that laptop that need to be saved. I have not contacted dell through phone yet because I believe that if they were to take the laptop in they would have to erase everything. what do you recommend I do?
thanks in advance
I have the same problem. I also get 7 beeps. The power LED flashes on briefly before the beeps but the screen stays dark. Did you have any luck fixing your problem? Dell says it is the CPU but my problem occurred immediately after I did an update back in July, about 2 weeks after my warrantee expired.
Seven beeps is a mainboard or (less likely) CPU failure - on just about everything built in the last few years, the CPU and mainboard are a single unit - you'l need to replace both together.
