BIOS Error Beep - Display adapter error (MDA/CGA) ?

2009-09-22, 18:44 PM

My T61p won't display anything. When I turn it on, I just get one long beep and two short beeps (which, according to the table in this website, - I'm assuming the BIOS is IBM - there is a Display adapter error).

How can I fix this?



P.S.: Before I figured out how to categorize the beeps, I've uploaded a video with the start up of my T61p: http://www.youtube.com/watch?v=8Nrl6yk3rPs

Hi arlab,

 

Sorry to hear about those new beeps, they are never good.

 

There is a ThinkPad General beep decoder. The T61p-specific decoder in the Hardware Maintenance Manual says the same thing:

 

1. System board. 2. LCD assembly. 3. DIMM.

 

If you are really lucky reseating/swapping/removing the DIMMs will fix it.

 

Warranty?

USB-C: Just cos it fits don't mean it works.
I don't work for Lenovo. I'm a crazy volunteer!

Thanks for the link.

 

I've replaced the DIMMs and connected an external monitor to the laptop, and I still got the same beeps so, unfortunately, that means it's the System board's fault...

 

Luckily my T61p is still under warranty. I know there is a webpage where Lenovo says which FRUs should be removed before sending the PC to a depot. Can anyone give me a link to that page? Also, is there anything else I need to know?
