Question about Dell Inspiron 6400 Notebook

2 Answers

Insprion 6400/1505 w/1GB ram and 120GB SATA drive - won't power up.

When I attempt to power up the laptop, the 3 indicator lights on the front panel light for about 5 seconds then go out and the laptop won't power up. The power brick has a green light and the battery works in our other laptop. I fear a motherboard or power supply failure. The issue began when our cat puked on the laptop keyboard. We attempted to power down the laptop to no avail and wound up pulling the battery while the laptop was live.

Its not powering the pc up this may mean a mother board failure if you say that the battery works on another pc, if you can still power your battery up with the mains using the laptop then theres no other problems so it is a motherboard problem

Cant find my motherboard pin out,2817,2388344,00.asp?tab=Specs

With all due respect, you have the manual in front of you now

That is unless you started unplugging wires already, and didn't make notes, drawings, or take photos.

Let's use the Asus Essentio CM1630 motherboard for an example.
Couldn't find a CM1730, but that's OK. We'll use this one for a general example,

Put your mouse cursor in the middle. Now move your mouse around, using the Zoom In feature.

If this motherboard were mounted in a computer case, it would be turned 90 degrees to the Right.
Bear that in mind.

The front of your computer is the Front Panel.
The area of contact pins on the motherboard, that the Main wires from the Front Panel go to, is the Front Panel header.
Goes by many abbreviated names.
PNL 1, FP1, PANEL1, etc.
(Panel 1, Front Panel 1, Panel 1)

Go to the Top/Right corner of the motherboard photo. To the 6 Blue SATA connectors.
Immediately to the bottom of them, is a white Front Panel header.
Two rows of contact pins sticking up.

You need to make notes, drawings, photo, whatever; of where the wires from the Front Panel, go to each one of those pins.
(Some may not be used)

How to know which wires coming from the Front Panel, are the Power On switch wires, Power On LED light wires, HarDDrive activity LED light wires?

Remove the Front Panel from the computer. If it is Not just a cover, EASE it off just enough to look behind it.

You usually can follow the Harddrive activity LED wires.
Harddrive activity LED is usually AWAY from the Power On switch, and Power On LED light.

There's two wires down.
Now look at where the Power On LED light is. Can you see wires going straight to it?
Two more wires down.

From process of elimination, you now know the last two wires going to the Front Panel, are for the Power On switch.

(The Power On switch, is part of the plastic Power On Button assembly. If you look close at the Power On Button assembly, you can see this)

THAT sir, is the MAIN thing.
I can guide you where the other cables go, as far as power cables, and Harddrive cables, and Optical Drive cables. (CD/DVD drive)

If you have already disconnected the Front Panel wires to Front Panel header on motherboard; you get to play a game(?)

Power Supply plugged into power, use a small flat tipped screwdriver, and touch two pins at a time.
When you get to the two Power On switch wire pins, the Power Supply will come on.

Now it is a process of elimination.
Use an LED with two wires, to find out what the rest of the pins are.
The rest of the contact pins in the Front Panel header.
Grab the HDD LED light, or Power On LED light.
You're getting a new computer case anyway.

Touch two pins, and the LED light blinks?
That's the HarDDrive activity LED light, pins.
LED stays on?
That's the Power On LED light, pins.

Either of those LED's are dim, (When the Harddrive is active, or when the computer is on), switch the wires around.
You have the Positive ( + ) wire mixed up with the Ground ( - ) wire.

Moving on.............
The 6 Blue SATA connectors on the motherboard:
If you look close you will see;
Or it may be,

The Harddrive plugs into SATA0 or SATA1.
Just depends on what the SATA connector numbering starts with.

The main optical drive, or a single optical drive; plugs into SATA1, or SATA2.
A secondary SATA optical drive will plug into SATA2 or SATA3.

(Look at the SATA numbering above, and you can compare side, by side )

HOWEVER, the beauty of SATA is; that you can plug whatever you want to, in ANY SATA connector on the motherboard; and BIOS will find it.

Plug the Harddrive into SATA 3? No problem.
Plug the optical drive into SATA 0? No problem.
BIOS will find the drive with the Operating System on it.
The Harddrive.
Then BIOS will know the other drive/s are optical drives.

(Make sure in the BIOS Setup utility, that the SATA connector on the motherboard you are using, is Enabled.
Otherwise BIOS will Not see the drive)

What cable from the Harddrive, and optical drive; plugs into those SATA connectors on the motherboard?
A SATA data cable,

Note the L-shaped opening in the SATA data cable connector.
Lines up with an L-shape on the motherboard connector.
One example of a SATA connector on the motherboard is shown.
This one is an Open design. Your SATA connectors on the motherboard, will be a Closed design.

Between a SATA data cable connector, and a SATA power cable connector, the SATA power cable connector is larger in width.
SATA data cable connector has 7-pins.
SATA power cable connector has 15-pins,

See the SATA harddrive example?
Note the L-shape is pointing DOWN. It is this way EVERY time.
Now you know which way to turn the SATA data cable's connector, when installing. 'Foot' of L-shape goes Down.

Wiring diagram emachine T5246


There's what I'm talkin' about!

The model number.

The eMachines T5246 Desktop PC uses a
Foxconn/Winfast MCP61PM2MA motherboard.

[You stated Foxconn/Winfast. I got that. Just letting you know ]

Guess what?
So does the Gateway GT5476E Desktop PC,

Click on - Product Views - in the list.

The front of your computer is the Front Panel.
The area of contact pins on the motherboard, that the Main wires from the Front Panel go to, is the Front Panel header.

If you need a pinout for the Front Panel header, click on -
S - Front Panel connector

The Top row is numbered EVEN. Starting from the Left side going to the Right;
Pins 2, 4, 6, and 8. There is NO pin 10.

[Colors going from Left to Right;
Orange/Yellow, Orange, Green, Green ]

The Bottom row is numbered ODD.
Starting from the Left side going to the Right;
Pins 1, 3, 5, 7, and 9.

[Colors going from Left to Right;
Red/Yellow, Red, Blue, Blue, Yellow ]

A) Pins 1 and 3 are for the HarDDrive activity LED (Light)
Pin 1 is for the Positive ( + ) wire.
If the HDD LED is dim when the harddrive is active, switch the wires around.

B) Pins 5 and 7 are a Reset switch, IF a Reset switch is used.

C) Pin 9 is for 5 Volt power. This was used by the factory. It is N/C.
Not Connected.

D) Pins 2 and 4 are for the Power On LED.
Pin 2 is for the Positive ( + ) wire.
If the PWR ON LED is dim when the computer is on, switch the wires around.

E) Pins 6 and 8 are for the Power On switch.

Any other connector info you need? Post in a Comment.


1) Ram Memory:
Uses DDR2 Sdram at 667Megahertz. (667MHz)
Maximum TOTAL amount for the motherboard is 2GB. (2 GigaByte)
Maximum Amount for each Ram Memory slot is 1GB.

IF, you just have one ram memory module, make SURE it goes in ram memory slot 1. (DIMM 1)
That is the ram memory slot closest to the Processor.

Uses a SATA harddrive, and IDE (PATA) optical drive/s.

Does have two SATA connectors on the motherboard, so it can use ONE SATA optical drive.

On those SATA connectors on the motherboard,

See the bottom SATA connector has SATA 1 next to it?
The SATA harddrive is supposed to be plugged into it.

However, the beauty of SATA is, NO MATTER WHAT SATA connector you plug into, BIOS will find that device.

Want to plug the SATA harddrive into SATA 1? No problem.
Want to plug the SATA optical drive(CD/DVD drive) into SATA 1?
No problem.

Want to plug the SATA harddrive into SATA 2? No problem.
Want to plug the SATA optical drive into SATA 2? No problem.

BIOS will find the device.

Can't read HD-- I/O error

"Joecolvette" has probably got it right, I've seen this before. The HDD enclosure circuit board has a fault. Can be resolved by replacing the enclosure. Plenty on ebay, just ensure you buy one with the correct HDD interface (Sata or IDE).

Alternatively, if you have a tower with a spare port, you could take the HDD out of the caddy, install it in the tower as a "Slave" (check jumper settings) ensuring the system drive is set to "Master". Then you can check whether the HDD itself is at fault.

Insprion 910 ac and power won't work

The power supply may not be putting out the correct voltage, and since the battery has been removed, "rule out" sub out the ram one at a time testing as you go, if no luck! remove the hard drive and reseat it back in place, still nothing, the motherboard is the likely source, I recommend having it assessed.

I am having hp 530 laptop with intel core duo inside,512mb RAM,80 gb hard disk.I want to upgrade my processor,ramand hard disk. can i do it ? upto what limit ?

Unfortunately I would have to say no, you won't be able to upgrade the processor. I located a user manual at

According to specifications you can increase the Ram to 2 MB and the hard drive should be a 120GB hard driver Sata

System Memory 1024-MB 533/667-MHz DDR2 SDRAM in one slot
Two SODIMM slots; supported memory 2048 MB2
Operates at a maximum of 533-MHz with 667-MHz memory
Hard Drive 120-GB3 5400 rpm SMART SATA

The processor will be limited to what the motherboard can support and it was designed for that 1.6 Ghz processor. Unfortunately it is very difficult to upgrade processors in laptop machines. I do have to ask how old this machine is. The specification indicates MegaBytes of ram and this is actually very little Ram in today's computing world. Most machines support at least 2 gigaBytes of Ram to start with.
