Sorry for the delay responding. Info comes from http://tech.groups.yahoo.com/group/Laptop_Repair/message/646 Joe K Sony Vaio Hi Joe I have a unit now with the MBX 49 board that is totally dead does not charge battery or work from a known charged battery. The small fuse at the rear F2801 is OK, 19V on input to Q2803 nothing out from one that I worked on earlier I noted that this should have 19 on the output. This is a fet and is not being swithed on as the gate is also at 19V not pulled low as for P channel fet.

SOURCE: how to reset mbx 160 bios for a sony vaio

To reset the BIOS read the information from this link.

In case of your laptop the easiest method would be using software from Hiren's Boot CD as it's pretty hard to open it up and reach for the CMOS battery or the jumper.

SOURCE: ihave mbx -160 ms70 sony laptop mother board ther is no power adapter is working pleas telme whatare the comapnents i have to chek in power section

A) Check the DC Power Jack.

The DC Power Jack is the jack that the AC adapter (Charger) plugs into. (May state DC_IN near the jack on the outside of the laptop case)

IF, I have it right, there is a DC Power Harness. The DC Power Jack is connected to wires in a harness, and the harness has a plug on the end. The DC Power Harness plugs into the motherboard.

http://www.laptoppartsexpert.com/i-131440-dc-jack-w-cable.html

[Instead of the DC Power Jack being soldered to the motherboard]

Remove the DC Power Harness, and with a multimeter set to OHM's perform a continuity check of all wires in that harness.
See if the DC Power Jack of the harness, is in good shape.

DC Power Harness checks out?
Problem is with the Power MOSFET's on the motherboard, or a ceramic capacitor, or two.

!O_O!

MOSFET,

http://en.wikipedia.org/wiki/MOSFET

Power MOSFET,

http://en.wikipedia.org/wiki/Power_MOSFET

Don't know who makes the P.MOSFET's on the motherboard, or what manufacturer number they are.
They are however, located Near the connector on the motherboard for the DC Power Harness, and they have 8 J-leads.

This is an example of a Fairchild Semiconductor FDS6675BZ
Power MOSFET. One example of a P.MOSFET used in this application, on a LOT of laptops,

https://docs.google.com/viewer?a=v&q=cache:oER5NNz8cwcJ:www.fairchildsemi.com/ds/FD/FDS6675BZ.pdf+Fairchild+FDS6675BZ&hl=en&pid=bl&srcid=ADGEEShOhWPjm_M-ROHme4iEMrztCTOd-28jNiy1hVLQQh_VOyv8zcXEVDB_iTQA6MuZO88UmRkDgjyW9j4CP2aIJ-4DS-h6JNM3lvxldeApQeecmz_DADCw1s7tmNLxfPknqX14SZP6&sig=AHIEtbS_rYUAeo_8rB9YHkW05ZjLqeH4Jg

Note the leads coming off of both sides. Those are 'J-leads'.

See if any of the Power MOSFET's, or Ceramic Capacitors, are burnt, and/or bubbled.

This gives you more information, but is using HP Pavilion dv6000, and Pavilion dv9000 series of Notebook PC's, as an example,

http://mayohardware.blogspot.com/2010/04/important-parts-on-dv6000-and-dv9000.html

Here you see the two Power MOSFET's used. One on top of the motherboard in the power section area, one on the bottom of the motherboard.

Looking at the second photo with the Alpha and Omega AO4407, Power MOSFET as an example, look to the right of the yellow circled AO4407.

To the right is a Ceramic Capacitor.
Rectangular in shape, and looks like there is a black wide band across the middle. There are two more above it. See if one, or more of these are burnt.

http://www.mouser.com/Search/Refine.aspx?Keyword=FDS6679

That's right. A Fairchild Semiconductor FDS6679 Power MOSFET is $1.01 USD, without tax, and shipping.

Just an example of cost.

http://www.mouser.com/Passive-Components/Capacitors/Ceramic-Capacitors/Multilayer-Ceramic-Capacitors-MLCC-SMD-SMT/_/N-b2cj?P=1z0ynasZ1z0vhw8

Scroll down. Average cost is from 9 cents to 80 cents USD.

Regards,
joecoolvette

The most common way that we know on how to reset or clear the BIOS password is to physically remove the power from the computer by disconnecting the power plug and then removing the Cmos battery for 30 minutes from the motherboard.

Another way is to reset the clear CMOS jumper on the motherboard itself. Both of the 2 methods mentioned works because most motherboards use a battery to sustain the

BIOS/CMOS settings for the motherboards PROM chip. So by cutting off cmos the battery power, the BIOS/CMOS settings will be erased.

cmos battery Under the keyboard or bottom of laptop - If you are working on a laptop computer the location of the dipswitch (almost never a jumper) can be under the keyboard or on the bottom of the laptop in a compartment such as the memory compartment.

Although on some motherboards the Cmos battery is soldered in

if this fails
click start type cmd press enter

At command prompt type debug
you will get a - prompt where you can type the following (<enter> means press enter, not type enter*)

A <ENTER>
MOV AX,0 <ENTER>
MOV AX,CX <ENTER>
OUT 70,AL <ENTER>
MOV AX,0 <ENTER>
OUT 71,AL <ENTER>
