Hello
Suddenly the mainboard DA061L Boxer Motherboard AM2 61 08120-1 from a slim PC emachines EL1200 cannot start and nothing shows up on screen.
If I connect the power the cpu fan is working by itself, without pressing power button.
If I press power-on button nothing happens.
I've already tried to put the cmos battery out and setting the bios jumper for reset, but it doesn't help.
Has anyone an idea, what's wrong? |

A known-good BIOS battery is in use? If the old one is low on voltage, then the real-time clock may not function, and the mobo circuits would not respond.
But do a careful inspection of all the capacitors on that mobo.. for any bulging tops or signs of leakage. More info about 'bad caps' at www.badcaps.net/ .
Do a voltage check with a digital multimeter, at the main power connector. Use any black lead terminal or ground point as common. Voltages should be within +/- 2% for proper operation. The -12 volt source can be off by 2 volts, but still within limits. The lead for the PSGOOD is a green wire at the back of the plug. It should show about +5 volts after the load has stabilized, to allow the mobo circuits to operate. If low, then no signs of life.
The eMachine line is known to have a PSU of minimal capacity.. and they fail frequently, usually taking out the mobo at the same time!

The cmos battery and the main power connector are OK.
I've tried with a completely new cmos battery and with other main power supply, that for sure is working on other but the same hardware, still doesn't work. |

I had a Boxer motherboard fail on me a few weeks back from a more recent series even. The build quality or lack thereof on eMachines is already legendary, they keep finding new lows... eMachines is the very reason I am no longer recommending Acer anymore.

Thx, according to:
http://en.wikipedia.org/wiki/EMachines
"In July 2004, eMachines began to shake the perception that their computers were of poor quality when PC Magazine reported:
Among systems less than a year old, eMachines users report the fewest serious problems. eMachines' low-cost PCs are less likely to need repairs than systems from any other vendor. Whereas only 9 percent of eMachines desktops less than a year old needed repairs, according to readers, the rates of comparably new systems from Dell and Gateway needing repairs were 11 and 15 percent, respectively. Only 1 percent of all eMachines systems needed to be replaced.[1]
eMachines was acquired by Gateway in March 2004 for $262 million in cash and stock. Under the deal, Wayne Inouye, CEO of eMachines, became CEO of Gateway, replacing founder Ted Waitt. It remains a stand-alone brand that is sold through retailers, catalog and online merchandisers. Gateway itself was purchased by Acer in October 2007.
In June 2011 eMachines released BIOS update version 1.09 for the netbook model eM350 which after flashing the BIOS caused the machines to permanently stop functioning (i.e., version 1.09 "bricked"/permanently damaged any eM350 it was installed on). The failure occurred on all eM350 netbooks on which it was loaded.[2] eMachines subsequently withdrew BIOS version 1.09 from its website." |

It can be me but that mainboard I talk about was in a slimline Acer box, not an eMachines.
Recently, (not 8 years ago) it just so happens that out of all the recent kit kit I encounter every now and then (the stuff just over the 2 year warranty period old), only the Acers seem to suffer from mainboards going out and power supplies going sour.
This may be caused by using known bad-brand capacitors in the power supply units to save costs, or by undersized heatsinks on the northbridge chips, I don't know. This is just my personal experience.
The reason I have no recent experience with eMachines is because I have forbidden anyone to buy one if they want to use it for much longer than the warranty period.
Do I hold a grudge against eMachines? Yes. For a reason. Acer used to be a reputable brand, not so any longer.

I spent really a lot of time and didn't have any chance to get this motherboard running, so I've exchanged it. |
