Question about E-Machines eMachines Desktop PC

1 Answer

Emachines t2542 i've had this computer for about 4 years now and recently its been acting up, when its just running its kinda loud, also i usually keep my computer in stand by and when i came home one day i find the light under the power button flashing rapidly and a weird ticking sound that went along with the flashing light. i moved the mouse, usually it brings the computer out of stand by, but no response. i kill the power to the computer and wait a little bit, plug it back in and the flashing and ticking persisted. i removed the side panal and listened, the ticking sound was coming from the floppy drive, i probably shouldn't have done what i did next but it stopped the ticking sound, i unpluged the floppy drive. but still no response from the computer.

Assuming you didnt leave a floppy disc in the drive causing windows to boot from floppy, if you have disconnected the drive you have to tell the bios not to look for the drive. Press F2 or Del while the pc is booting up and in the first window may be the option Halt on all errors, dissable this if it is enabled and also there should be a section to check for the floppy drive on boot up (this can stop the boot sequence if not found), dissable this also, this part could be in the main window where it shows the date and time or in the advanced cmos settings. If you have changed anything save settings and exit. Any pc will boot without the floppy drive, so there must be something stopping it from booting and at the moment it points to the floppy.

Modem on and nothing on screen and fan runs loud

It sounds like one of three things. Two are pretty unlikely.1. RAM has gone bad. Really unlikely. Usually if this happens the computer will not boot but beep at you.2. Video Card has gone bad. Also unlikely. Usually the computer will sound like normal except you won't have any video.
3. Motherboard has gone bad. Most likely. The Motherboard has either suffered a voltage shock or has blown a component. The only real way to get this repaired to by going through Gateway / Emachines.

Front power switch broken. Bezel won't come off easily. Thought we could just get a switch and install on the back but don't know which of the colored pairs of wires go to the original switch in the...

I would suggest this generic Power On switch,


and the Red, and Black twisted pair of wires go to the Power On switch.

Your statement of ,"....don't know which of the colored pairs of wires go.....", leads me to believe you may have all of the Front Panel wires disconnected.

How about information as to where ALL the Front Panel wires go?
(Provided I have correctly interpreted your statement)

Back in the time that the eMachines T2542 was made, TriGem was the motherboard manufacturer.

The Model Name of the motherboard is Imperial, and the Model Number of the motherboard, could have been one of four variations offered.

Model Name: Imperial
Model numbers could be G, GL, GV, or GLVE
(Imperial G, Imperial GL, Imperial GV, or Imperial GLVE)

ALL four variations used the same Front Panel header.
(The connector on the motherboard the Front Panel wires connect to, is named the Front Panel header)

I would like you to view this page,

Scroll down to the heading -
Trigem Imperial Front Panel Header Pinout.

A) Pins 1, 2, and 3 are for the Power On LED light.

B) Pins 5 and 6 are for the HarDDrive activity LED light.
(Pin 4 is not used. NC. No Connection)

C) Pins 7 and 8 are for the Power On switch

D) I wouldn't connect any wires to Pins 9 and 10, nor Pins 11 and 12

E) Pins 14 and 15 are for the Reset switch. (The button you press to restart your computer.
If the T2542 doesn't have a Reset switch, don't worry about it. There are many other ways to restart your computer)

F) Pins 17 18, and 20 are for an internal speaker.
This speaker is used for BIOS Beep Codes.

In the chart to the right, you will see GRD used many times.
GRD stands for Ground.
ANY Black wire in the twisted pair of wires, is a Ground wire.

Most of the eMachines I have worked on, use a Red, and Black pair of twisted wires for the Power On switch.
I could be mistaken on the T2542.

Best method, is to follow the color code of the wires that come from Pins 7 and 8, and be sure.

Good day sir, hi, the realtek you downloaded maybe is not the correct driver, the driver is the ALC202 from this website:

You can visit this site for the driver:

Definition of beep codes on power-up beep-------beep beep beep-------beep beep beep---------beep on a t2542 emachine

Sounds like a video error. It may be caused also by a bad memory, but I suspect problems with video.

When you say out, do you mean they are broken, or just disconnected? Most of these computers have a plug on the end of the wires to the front panel and it just plugs into the system board. If you look at the board you'll see where the front panel wires go. Sometimes it's hard to read the small type, but there are labels on the board that tell you what connector does what.

Hi. could be a few things
1st thing if theres no power going to the base unit, the power supply is gone will cost about £20 for a new one.

theres a few other things it could be but less likely. i suggest trying the above..

Emachine T3508 Loud Loud Loud

The only sure way to quiet it down is to replace the hard drives with newer ones, that you have selected based on their noise rating, AND to replace all the fans in the machine with fans that you have selected based on their noise rating. I did this for my self-built machine last year and never regretted spending the money on new drives and new fans. It's SO much quieter! ;)
