With too many reset tools about Windows in the Internet sometimes we will not know which one will be better. As for paid reset tools so many you can see though their price can be different. I have used Windows Login Recovery, which can support most OS and can reset admin or other local accounts password. And it is safe and effective. The most important is that it is the lowest price among paid tools. Windows Login Recovery Secure Windows Password Recovery Tool

A) AC adapter (Charger) is bad.Use a multimeter, and check it out.[ DC Voltage. Test plug of cable that plugs into laptop.Positive (Red) probe lead of multimeter, to Center Hole of plug on AC adapter.Negative (Black) probe lead touches outside cylindrical metal shell.You should read close to 19.5 Volts (DC) ]AC adapter checks out OK?B) DC Power Jack is bad[The DC Power Jack is the port on the laptop, that the AC adapter plugs into. On laptop may be marked DC_IN ]Damage to DC Power Jack prevents laptop from charging, or running strictly off of the AC adapter.Battery removed take a No.2 pencil's eraser, and see if you can gently move the Center Pin, of the DC Power Jack.ANY perceptible movement means replacement of the DC Power Jack.The pin itself may not move, and the entire jack moves.The good news is the DC Power Jack is not soldered to the motherboard.It is soldered to a separate, therefore replaceable, small circuit board,http://www.parts-people.com/index.php?action=item&id=3698Click to enlarge. In the photo the DC Power Jack is at the back on the right.This is is what the DC Power Jack, looks like not installed on that small circuit board,http://www.elept.com/dc-power-jack-for-dell-inspiron-xps-m140-m1710-m1210-m2010_p2971.htmlLooking at the view on the right, note the pins sticking out.You are looking at the back view, and the jack is laying on it's side.The pins go through the laptop's motherboard, and are soldered to the motherboard.Where the pins are soldered to the motherboard is a solder connection. Commonly referred to as a Solder Joint.Plugging in, and missing the hole of the jack, can cause the AC adapter plug to damage the DC Power Jack, by bumping into it.Bumping into the plug of the AC adapter, while plugged into the DC Power jack, can cause damage to the jack.Can cause cracking of the above mentioned solder joints. This leads to an intermittent contact, and eventually no contact, of the DC Power Jack TO the motherboard.In this case the solder joints are just re-soldered.Damage to the body of the jack itself means replacement of the DC Power Jack, or replacement of the USB/DC Power Jack circuit board, itself. (Unless you, or an acquaintance can un-solder, and solder real well, the option may be to just replace the USB/DC Power Jack circuit board)DC Power Jack proves to be OK?Problem is one, or more Power MOSFETs on the motherboard.These determine if the Battery needs a trickle charge, or a full charge, or no charge at all. Also determines if the laptop is to just run off of the AC adapter, and not the Battery.This example is for HP Pavilion dv6000 and Pavilion dv9000 series of Notebook PC's. You can use it for cross-reference information.(Location of the Power MOSFETs on your laptop's motherboard.

Looks like motherboard replacement to you?OKLet's price a Fairchild Semiconductor International - FDS6679 - Power MOSFET,http://www.mouser.com/Search/Refine.aspx?Keyword=FDS6679If you buy one the cost is $1.01 USDLook to see if the Power MOSFET/s are burned. Blackened, bubbled, or blistered.There is one more small component, that if bad will produce the same results;Ceramic Capacitors.Look back at the Mayohardware blog. Look at the second photo down with the AO4407 Power MOSFET circled in Yellow.Note the small rectangular shape to the immediate right, that has the wide dark band on it. There is one above it, one above that, and one to the right of the top one.See if any of these, (No matter what the size. Look at all of them), are burned. Blackened, bubbled, or blistered.http://www.mouser.com/Passive-Components/Capacitors/Ceramic-Capacitors/Multilayer-Ceramic-Capacitors-MLCC-SMD-SMT/_/N-b2cj?P=1z0wquyZ1z0t6fgNOT stating these are ones to use.

There are only three moving parts on your laptop. One is the cooling fan. So for it to make this sound, it can have something stuck inside the vent slots, or very dirty so that the bearings are busy seizing. the other device is your hard drive. So back up your date first of all, Then take your laptop to a technician that can open the machine and check, If you keep on operating it with this condition it will cause some damage soon.Or you have a CD/DVD stuck in your Optical drive- just check that as well
You should have a "FN" key on the keyboard and one of the "F" keys should have a symbol that looks like the touch-pad, hold FN while using this key should disable it, failing this in control panel, then mouse and pointers, you should have touchpad setting there should be a disable button/radius.
Most laptop or notebook computers feature enhanced BIOS security, and
BIOS passwords on laptops are hard to bypass. Several companies offer
laptop security chip services that can be used to bypass the BIOS
password on Dell laptops or notebooks and reset the security. They can
provide a master password from the Dell Service Tag of your Dell
laptop. This master password will allow you to bypass the existing
password and enter the BIOS and reset the unknown password. To generate
the master password they need to know the Dell Service Tag of your
unit. Dell Master Password Recovery does not require soldering or
disassembly of the laptop and supports most Dell models.
Dell
BIOS passwords can also be reset by replacing the laptop security chip.
Passwords can also be recovered from security chips that have been
removed from laptop or notebook systems. These passwords may be
required to attempt to unlock protected hard disks. Passwords recovered
from these chips are the original BIOS passwords and may be the same as
the hard disk password, but are not guaranteed to be the same and may
not unlock the hard disk.These are usually damaged in the process of
recovering the passwords and are not suitable for replacement into a
computer.
this is from the manual for your computer. you need to get it on both monitors simultaneously.When you start the computer with an external device (such as an external monitor or projector)attached and turned on, the image may appear on either the computer display or the externaldevice.Press <Fn><F8> to switch the video image between the display only, the external device only,or the display and the external device simultaneously.
if your computer came with a motherboard disc the sound drivers could be on it
click start control panel administrative tools computer management device manager scroll to sound video and game controllers you might see a yellow question exclamation mark? ! or a red X Right click to reinstall drivers
click start control panel sounds and audio volume advanced speakers make sure you have selected the
(appropriate speakers) also audio you will find 3 drop down lists make sure you have selected the correct speaker settingsthere
click start control panel sounds and audio devices select advanced there might be a tick in the mute box untick it
if you dont have a motherboard disk you will have to download the drivershttp://download.cnet.com/2000-20_4.htmlon the home page you should see a search tab just type in what you are looking forIE: motherboard name audio driver you might have to try a few times to get it righthope this helps
