There are no fuses that you can see on the outside of any laptop. They are on the motherboard and they are inside the battery itself. You need to give us more info or perhaps attach a picture of the issue and explain how you shorted what.

This is mostly a true answer: You can use Windows Vista 64-bit drivers in a new Windows 7 setup...There are a few exceptions, from what I've discovered: Several types of HD Audio drivers will not cooperate, and some WIFI drivers won't either. Here is a link to get the Dell Windows Vista x64 drivers to get you started:

This is usually because the wireless key code (password) was entered incorrectly or has got corrupted. Go to "view wireless networks" (from the icon at bottom right of your screen) find the one it says it is connected to and click "disconnect". Then re-boot the PC (not strictly necessary but a good precaution), go back to "view wireless networks", find the correct one for your router and connect to that with the correct code key. I have seen it where the code key has been changed from the one written on the sticker on the router and if that is the case the "fix" will be more complicated.

Also, if this does not work, go to "control panel" then "Internet options" and then "advanced" and find and click on "reset". This puts Internet Explorer back to the default settings and often fixes it (though NOT if yours is an incorrect wireless key issue as talked about above) - Your home page will change to MSN but that is easy to change to your preference.

Hope this helps

Use an external USB WiFi adapter. I prefer to use nano (very small) Edimax WiFi adapter. It cost less than $15

  1. Open the cover that is over your HDD
  2. Remove the Hard Drive from it's casing
  3. Now replace the HDD ensure everything is connected properly
  4. If possible, power up and listen for the HDD to spin, if it's making no noise or a very noticeable clicking noise it's time to purchase a new HDD
  5. If not power on anyway and see if you get the same error.
  6. Try a spare HDD instead, this would indicate if the HDD you have now has failed also
Let me know how you get on

Inside? Yes. (If 'charger' is good)

Diagnostic flowchart:

A) AC adapter (Charger), has to be KNOWN to be good, before going on.
Used on a working laptop to see, or multimeter is used to check Voltage (DC)

The plug end that goes to the laptop, from the AC adapter, has a Center Hole, and a cylindrical outside metal shell.

The Function knob is set to DC Voltage. If just a symbol, the symbol is a dotted line over a solid line.
If more than one DC Voltage scale, the Function knob is set to the 0-50 Volt DC scale.

The Positive (Red) probe lead of the multimeter goes to the Center Hole, and the Negative (Black) probe lead of the multimeter, goes to the cylindrical outside metal shell.

You should be reading 19 Volts DC.

Also have an assistant gently wiggle the cable FROM AC adapter TO laptop, and the power cable TO AC adapter.
If there is a fluctuation on the reading, there is a broken wire, or wires, in one of those cables.

B) Check the DC Power Jack.
This is the jack on the laptop (DC_IN) that the AC adapter plugs into.

Has a Center Pin, and an inner cylindrical metal shell.
Battery removed, use an eraser on the end of a No.2 pencil, and see if you can GENTLY wiggle the Center Pin around.

ANY perceptible movement of the CENTER PIN, means replacing the DC Power Jack,
(By the way, is it an 8510p, or 8510w?)


Any movement of the rest of the DC Power Jack (Body), means replacing it; or may just mean the solder joints are cracked, and can be re-soldered.

C) AC adapter and DC Power Jack checks out?
Problem may be with Power MOSFET's on the motherboard, and associated MLCC's.

(Multi-Layer Ceramic Capacitor, and they are SMD/SMT just like the Power MOSFET's.
Surface Mount Device/ Surface Mount Technology)

Power On Password & Hard Disk Password
With your next laptop you should protect it with a Power On Password AND put a password on your hard disk. This will stop anyone from using your laptop and if they move the hard disk from your laptop to another laptop they cannot access the data on your hard disk with the hard disk password.
BUT you need to write down or remember these passwords; if you lose or forget them you cannot gain access to your laptop.
There are no backdoor passwords to remove these passwords.
To set up or change these passwords, go to the BIOS configuration - then security configuration. http://techtips.salon.com/reset-hp-laptop-bios-password-1476.html

When you connect the power adapter into the laptop, does the power LED light up? If not then - The battery adapter or the adapter's power lead or the laptop's power socket could be faulty. Check power adapter's DC plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard. This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. If you cannot DIY then I suggest you get a quote first.
