Dell studio 1558 wont start up beeps 7 times

SOURCE: I dropped my Dell Studio 1737 on the power button

Hi !
First let's check if the button is broken (the one you don't believe is a part of the motherboard), or if it is just the plastic/metal cap of the button stucked on it's push way!

Try GENTLY touching the cap of the button in left-right and up-down directions.
If you can feel the cap doesn't moves, try (again) GENTLY to unstuck the button cap. Keep in mind that it has only a part of a millimeter to go.

If the cap is not stuck, then probably the power button is either damaged,
or
when you drop your laptop, it went more far then the cap can push it normally (I said before, a part of millimeter is enough).
It should be checked.

In both cases the laptop should be opened.
I suggest NOT to do that by yourself, it is a complex thing to do!

Replacement of the button is also hard thing to do, no matter if it is a part of the mutherboard or not, and should be done by qualified servicer.

Regards.

SOURCE: Dell XPS M2010 Starting Problems

Ok. Here is the thing. I hope everybody sold their problem, but I will just post for others who may experience the same thing.

1st believe it or not : there is nothing wrong with motherboard, as when you press the power button, computer will shut down. with defective motherboard it will just continue running untill you will unplug it.

2nd believe it or not : it can not be battery issue or hard drive issue, because it does not make any scenes in any way. I have to agree that hard drive on the right is semi-correct answer.

REASON:

IT is video card that messing up everything. And it is located right under right hard drive. That's why when somebody removed hard drive he/she accidentally corrected the cooling system of video card , which returned M2010 to live.

CONFIRMATION:

1. First remove the top cover from the computer. There are 2 sides the plastic things. If you look at the back of your laptop you will see 2 small holes , one on every edge of the back. You stick something there it will loose the front cover.
2. unscrew all the screws hat have ">" or "<" signs next to them. there are something about 15-16 screws in total: this will allow you to open the cover under wich you can find the motherboard and stuff. When you open the cover pry to start the computer, and you will see that fans will not start even after 1-2 minutes after you hit the power button.
3. Remove the right hard drive and under it you will find screws A, B, C, D (silver) and also 1,2,3,4 (black) unscrew the black ones first, them remove video card with the cooling mechanism. now try to turn on the machine. you can see that after like 20-30 seconds fans start working which means that motherboard is fine and it was the video card that was giving problems.

SOLUTION:

1. I am not sure what causes the issue but I have fixed it this way:
uscrew silver screws and disconnect cooling part from the actual video card.

2. clean both, video card and cooling system not touching sky blue foam ICs. That staff is needed to cool the chips on the video card.

3. let them dry for an hour or so after cleening, than apply some Thermal compound, thermal paste and re assemble the video card with the cooling staff. (mek sure no screw is loose or something)

4. put it back and turn on the computer. If it works , whell .. it works now :)

if not then either you levae some liquid on the video card or screws are loose. try to play a bit with screws. but my personal suggestion is just to wait for a minute or two until video card gets hot and fixes liquid problems itself :)

Try it. It worked for me perfectly ...

Check the BIOS for PC Health settings. It is possible that you have put a low value for "Critical Temperature", which makes the Laptop to turn off.

Testimonial: "Yes, this has been helpful. This could be an important clue. I wonder, however, why it would not turn off every 30 minutes throughout the day then. "

SOURCE: my dell studio 1558 has not been working since

If the system is 2 months old, your best bet is Dell Tech Support as the system should be under warranty. If you hold the D Key and press the power button this should run the LCD BIST and you should get 4 solid colored screens. If you don't the LCD is bad. If you do, then the issue is likely the video card.
