This machine was working just fine last night, but I opened it up this morning to put a new WiFi card in it and since then, it has refused to boot up. The behavior is this:
1. Press power button
2. System shows Lenovo BIOS/Diagnostics screen
3. Clicks and reboots
I can get into the BIOS no problem and tweak settings all day, but as soon as I attempt to boot it, the speakers click and the system reboots.
I have attempted the following:
1. Use the original WiFi adapter that I removed
2. Tested new/different RAM SODIMMs
3. Removed the batteries and discharged the capacitors
4. Removed the batteries and run on AC power only
5. Restored BIOS settings to default
6. Attempted to boot to Ubuntu from USB (Same behavior as above)
7. Removed all motherboard screws in the case that one might be causing a short
8. Experimented with BIOS settings such as UEFI/Legacy
I think that's about it. But I'm not sure where to go from here and any ideas would be appreciated; let me know if I can provide more information. This computer has been fully disassembled and reassembled by myself in the past (several times) in order to replace various components and do general troubleshooting and I've never experienced this issue with it.
Thanks
I've forgotten to mention that it also won't run its diagnostics from the BIOS. It just reboots instead.
