How to fix Lenovo R61 graphics card? With FIRE! ;-)

2014/03/05 ludek.vodicka Leave a comment

Last night my Lenovo R61 seemed to be dead. It doesn’t want to boot up and the only thing I saw was this screen with some black/white lines:

I started googling this problem and it looks like this issue is quite common for this type. But then in the middle of the night I found the solution that I hadn’t believed it could work. But as the notebook still wasn’t running, I said to myself that there is nothing to lose.

Here is the magic. It’s sufficient to heat nvidia chip by a flame for about 15sec.

First of all, it’s necessary to disassemble notebook and detach heatpipe:

After that you need to cover the rest of notebook except nvidia chip:

And as last step use any torch to heat chip to 700C for about 15s:

And that’s it. Now assemble notebook back (if it is possible :-)) and run it:

Here are two videos from youtube:

Used software

How to fix “The device, \Device\Ide\iaStor0, did not respond within the timeout period.”

Link with detailed description of this problem.

Short how to fix:

regedit
open HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\iaStor\Parameters\Port[0-n]\
set LPM=0, LPMDSTATE=0, and DIPM = 0

if your registry doesn’t contain this key, you have to add them.

Add new key "Port0".
Add new "DWORD" value named "LPM" and value leave 0.
Add next two "DWORD" values named "LPMDSTATE" and "DIPM".

Another advise how to fix this error

This method is originally referred in MS Technet forum:

Also the issue may be the result of Aggressive Link State Power Management (ALPM) on the PCI-Express bus negotiating a lower power state for the link between the controller and disk when there is no activity. When ALPM works, disk requests are queued, the serial link revived, and the queued requests are sent to the relevant disk; this requires a disk that supports ALPM.

1.       Click Start button, choose Control Panel.
2.       Move to Control Panel\All Control Panel Items\Power Options. Click Change plan setting in your current power plan.
3.       Click “Change advanced power settings”, move to PCI Express-> Link State Power Management, turn off the option.
