Edge E520 will not turn on [ Edited ]

[samsam]

Hi,

Yesterday I turned off my Notebook (also, no any problems). Today will not turn on!!!!. I tried this steps too:

1- unplug the AC adapter and take out the battery. Then, push the power button 10 times in a row at one second intervals. Next, push and hold the power button for 30 seconds. Then put the battery back in and pushed the power button, but not turn on.

2- unplug the AC adapter and take out the battery. Then, push the power button 10 times in a row at one second intervals. Next, push and hold the power button for 30 seconds. Then put the AC adapter (without battery) and push the power button, but not turn on.

If AC power adapter is connected, Power-status indicators is off. 

Note: I did not update Bios and etc., I have not external devices. I installed just Windows Server 2008 R2 and worked fine.

I want to know what happened!!!!

Thanks

Regards

A number of us have had similar issues, at least with E420s.  The fix to this is to send it to a service center and they will replace the motherboard if the system is still under warranty. I'm on my second fix to this in 4 months!

This problem appears to be pretty pervasive, and I believe there is a design issue with the Edge series.

ADMIN EDIT

If you are experiencing these symptoms, please contact support regardless of warranty status.  There may be additional provisions (depending upon qualifying factors) to assist you - support should be able to determine.

it is to do with a batch of faulty EEPROM chip used in the Edge series produced at the end of the 2011.

Great. I just had this same issue. Fortunately its covered by warranty. But still a major PITA.

All,

As Mtemp suggests, if you have experienced this issue, you might try a battery reset. the battery reset as described in this KB article.   (edit - corrected)

If that doesn't work - it is likely a system board fault and you should contact service - see my updates to the solution post above.

@Mark the link provided is for the E220s/E420s reset button.

Not a battery reset for the E320, E420, E520 machine.

I've had the same issue of No Power/No light twice already on my ThinkPad Edge E520 that was mfg 11/07, right in the middle of the problem EEPROM manufacturing period.   Lenovo has replaced the m/b twice and the last time replaced the DC Sub Card as well. 

I only have about 3 months left on my warranty and haven't been able to convince anyone thus far that the warranty should be extended w/o cost.  If the EEPROM issue is well known, why are they replacing m/b's that have the same problem?  If the pattern follows true to form, the next failure is likely to be when I'm just our of warranty. 

Does anyone have info of a about how many EEPROM failures have occurred in the Edge E520 series?    When I asked about this, was only told there haven't been enough to issue a recall.  I feel like I have a ticking time bomb and can't do anything about it other than paying extra for an extended warranty.  Anyone have suggestions on how to proceed with Lenovo warranty folks?

when was the second E520 motherboard replaced the second time?

The problem was only apparent later on. Regarding no. of failures that sort of information would be only available to the very high level management, and would be confidential.
