I have an emachines ET1331G-07w.....I cannot boot up windows. My screen is black and reads.......Reads......Reboot and select proper boot device......Tried alot and have no solution?? TY


Usually this error message means the computer doesn't "see" your hard drive. Remove the power cord then remove the side panel of the computer case. Check that the hard drive power cable and data cable are both plugged in firmly to the hard drive and to the motherboard. Plug the power cord back in and try booting up.

I have an Emachine D620 5133 Laptop that the screen stays solid white when powered up, any ideas?


No ideas

Just definite facts

Problem is;
A) Graphics chipset
Or.
B) Video Cable
Or,
C) Screen Inverter
Or,
D) LCD screen

Diagnose
LOT of reading ahead.

1) Graphics chipset:

Connect a VGA monitor to the blue VGA port, on the right side of the laptop.

http://www.geeks.com/largePic_all.asp?invtid=D620-5133-OB&pic=D620-5133-OB-box.jpg

This is a general example of a VGA port (Connector), and VGA Cable,

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

You can use a CRT type of monitor (Looks like a small TV), or a flat LCD screen monitor if it has a VGA Cable.

Turn the monitor on. If a CRT type allow it to warm up
Turn the monitor on.
By factory default settings the display should show on the external monitor.
IF not;

There are at least 3 display options;
A) Internal monitor of laptop ONLY
B) Internal monitor of laptop AND external VGA monitor
C) External VGA monitor ONLY

Press, and hold down on the Fn key, and at the Same time tap once on the F5 key.
The F5 key is the Display Toggle-Over key.

Still no display on external VGA monitor?
Hold the Fn key down again, and tap once more on the F5 key.

No display, (Or solid white), on external VGA monitor, suggests problem with graphics chipset. If this is the problem post back in a Comment.

Good display?
Problem is Video Cable, or inside the Display Assembly.
(screen Inverter or LCD screen)

There are no eMachines D620 service manuals, available on the internet for free that I have seen. Supposedly a few paid for versions, but I have my reservations about that.
(Probably a Generic User Guide, which you can get for free)

I also have never worked on this model yet.

But this isn't rocket science, and this isn't 'my first rodeo'.

2) Video Cable:

The Video Cable plugs into the motherboard, in an area under the Keyboard, and under the Palm Rest Cover.

Judging by;
A) Top View of motherboard,

http://www.ebay.com/itm/eMachine-D620-Motherboard-48-4BC01-011-MBN240100-08226-1-Yukon-MB-/121076931939?pt=US_Motherboard_CPU_Combos&hash=item1c30bf5d63

Set your mouse cursor in the middle of the photo. This enables the Zoom In feature.

Looking at the rectangular metal plate, with the opening in the middle of it; come from the Top/Left corner.

See what appears to be a fairly long white strip?
That is where the Video Cable plugs into the motherboard.

Now here is the D620 with the Keyboard removed. (And Display Assembly),

http://www.ebay.com/itm/eMachines-D620-Motherboard-CPU-base-assembly-/110847874891?pt=Motherboards&hash=item19cf0c574b

Here you see the white connector again.
Middle, and towards the Top; in the small rectangular opening.

The Palm Rest Cover has to be removed, to access the Keyboard Cable's motherboard connector. This connector.

Going on....
The Video Cable then goes up by the left Hinge, and then up into the Display Assembly.
From there the main portion of the Video Cable, connects to the back of the LCD screen.
There is also a separate small cable, coming from the Video Cable; that connects to one side of the screen Inverter.

Example of the Video Cable,

http://www.ebay.com/itm/eMachines-D620-LCD-Video-Cable-50-4BC03-021-/130862506637?pt=US_Video_Cables_Adapters&hash=item1e7803628d

The white connector you see at the bottom, with the black pull strip; is the motherboard plug connector.
The small cable extending to the Right, connects to the screen Inverter.
The large connector shown at Top, connects to the back of the LCD screen.

Just from normal repeated opening, and closing of the laptop; the Video Cable may become pulled on, and/or pinched.
This can cause a loose connection at the motherboard side, or LCD screen side.
Screen Inverter cable connection may be pulled loose also

Can also cause damage to the Video Cable. Stretched/Broken wires

The procedure is to;
A) Remove ALL power. Remove the AC adapter (Charger), and Battery.

B) PHYSICALLY check to see if the motherboard connection is tight. Try to plug in tighter.
Reinstall power. Turn laptop on see if this was the problem.

No?
Remove all power again. This time remove the Display Bezel, and see if the Screen Inverter cable is connected tightly.
At this point it is just going to be a visual observation, and record.

Next is to check the LCD screen connection of the Video Cable, and it may loosen the Screen Inverter connection, anyway.

[The plastic frame in front of the LCD screen is the Display Bezel,

http://www.ebay.com/itm/eMachines-D620-LCD-Screen-Bezel-41-4BC01-001-/300798380595?pt=UK_Computing_Other_Computing_Networking&hash=item4608fb0a33 ]

If plugging the connections of the Video Cable in tighter, does no good; the Video Cable is then checked for continuity.
A multimeter is used, and set on OHM's. (1K)

Electricity is sent through each wire. The reading itself isn't as important, as just seeing IF there is a reading.
No reading indicates stretched/broken wire.
You can take the Video Cable, down to the nearest small computer repair shop; and have the resident tech check it out for a few bucks.

The Video Cable MUST be ruled out as the problem, before going on. Otherwise you may be buying parts needlessly.
(LCD screen? Around $70 to $100. You have seen the price of a Video Cable)

Video Cable proves to be good? Go on.

3) Screen Inverter:

The screen Inverter is located behind the Display Bezel, and mounted to the bottom of the LCD screen. (Screen Frame)

To test a screen Inverter requires a sensitive multimeter. Read fairly expensive,

http://www.fonerbooks.com/test.htm

Do to this, the ease of access to replace, and the general low cost; the screen Inverter is just replaced,

http://www.ebay.com/itm/LCD-Power-Inverter-Board-for-eMachines-D620-Backlight-Replacement-for-Screen-/120819595221?pt=US_Laptop_Screens_LCD_Panels&hash=item1c2168b7d5

If this doesn't repair the problem, the problem is the LCD screen.
Replace.

I can guide you, and I believe step by step; if you wish to attempt repair.

My custom built computer has a the m7vig400 installed and i can't formatt my new harddrive because the fan on top of my processor will not come on why ? it came on with a 16 head hard drive how do i...


First, make sure you plug the power from the fan back into the motherboard & try it again. Did you do anything else besides just pulling out your old hard drive & putting the new one in? The CPU fan is completely independent of the CPU fan. You can start up you system without ANY hard drives & the CPU fan will come on if it's plugged in & the power supply is working etc. If you make sure the fan is plugged in correctly & the fan still doesn't come on, I suggest you temporarily put your old hard drive back in & firing things up. I'm sure you will find that the fan still doesn't work.

All that said, if the CPU fan isn't working (& everything else is), then it's a bad fan or motherboard. It's not necessarily a bad motherboard. Sometimes there are jumpers that control that sort of thing. I'm not sure exactly what that motherboard does. I have had this exact motherboard for years & as long as the fan is plugged in (& the power supply is working), when you start things up, the fan comes on.

One last thought, try flipping the power supply switch in the back to reset the power supply before you press the button in the front. Good luck...

Have a M7vig400 Mobo that is stuck at BIOS POST code 00 no beeps no video, any idea ?


Usually this means another hardware component has failed.
To troubleshoot, unplug everything from the motherboard except the CPU and memory to see if you get video.
Probably OK to leave the mouse and keyboard plugged in.
If still nothing, try removing one of the sticks of memory and then the other.
If you do get video, the primary culprit would be the CD and next the HD.

I'm assuming that the power supply is OK, but that isn't always so. I've seen computers that will boot but not correctly when part of the power supply goes bad.

Hi birm,
I can tell you that most likely the white wire is the ground wire. The others are positive. The two manual found on eMachine's site does not provide enough of detail.
In this manual see;
Replacing the front I/O Panel (Pages 168, 170 see number 5).
http://downloads.emachines.com/userguides/8511279_eM_NG3_chassis_HW_ref_en.pdf

The information is not specific enough, my guess is the front panel connections is the cable to the far right. (Looking at the picture).
You can try by looking at the picture & hooking the cable as shown.
The white colored wire seems to face to the right. Than try the power on button. If system does not come on, turn the connector 180 & reconnect. Try the power on button on the case.

Listed at the bottom of the link below you can either chat with a tech or call tech. (Main site for the T6522)

HI! I was cleaning the inside of my e-machine W3502 and I putted off the 3 cords labeled Power LED green in color,HDD.LED red in color, and the POWER SW. Now i don't know how to put them back on in order....


look on the motherboard where all the cables are plugged in, It should list on the board in small letters what plugs in there. whats written on top goes on the top pins & bottom list should be the bottom pins.
