Good morning,
I have a problem with Lenovo T580, which after error code 0288 suggests a problem with the display. I checked the display and it works on another laptop. I replaced the display cable with a new one. I programmed another BIOS (downloaded from this forum) and I still have the problem of a dead display - there is an image via HDMI, and the system does not detect the built-in LCD at all. The problem appears to be hardware. What can I check to confirm or disprove this? I found many threads on the Internet related to this problem 0288, but without specific solutions. Please advise.... -

Hi, my laptop suddenly shut down while it was running. When I try to turn it back on, the screen stays black and it emits a melodic beep.
I used Lenovo's SmartBeep decoder and it returned error 0284:"TCG-compliant functionality-related error (possibly BIOS code validation failure)"
I then tried to enter crisis BIOS recovery mode by pressing Fn + R at boot. The melodic error code changes, but nothing else happens regardless of whether a USB is inserted. I receive another...06-16-2025, 12:06 PM -
Hello, I have a problem with this computer.
After connecting the power supply, the keyboard lights up and the touch bar works, you can click on it and it even illuminates the keyboard. When the fan is turned on, it turns on and off. the processor heats up. I have tried different bios but with no success, the same signs. It doesn't charge the battery either. when starting, it takes 20v and about 0.650a, after some time it drops to 0.350a and 5.2w. Has anyone solved the problem with this model?
Will it be a RAM or CPU problem?
below is the computer details

Hello guys,
I have a problem with charging circuit in this laptop. Unit came with no power at all (USB-C meter was cycling turning off and on). I discovered that when I unplug battery laptop works on charger only. So after few measurements I found shorted 1st dual mosfet AONY36324. Unfortunately i was not able to order exact this one, so i ordered AONY36352 which i believe is the similar one. Now the problem is, when i connect battery and charger USB-C meter is not cycling anymore, it starts charging (reading 20V@2,7A) but after few seconds it is going down to 20V@0,20A and laptop...
