Screen black, unable to power on, no BIOS display, keeps restarting.
In short, the 8-year-old laptop stopped working after a black screen and no boot. It won’t even turn on BIOS. I tried several fixes but nothing helped. The battery was removed, charger taken out, and I checked the power button repeatedly. Results were consistent. Hard drives are fine, RAM is new and working, and disks are not old. The market value is about $300. Repair costs around $55 per hour or $189 at GeekSquad. Maybe swapping the RAM could help?
Do you have one or two RAM modules? If you remove one and see if the system starts, try the other. If it doesn’t boot either way, both RAMs might be faulty or the issue lies elsewhere. It could be the CPU lacking power or the motherboard itself. Power cycling usually points to a motherboard problem, especially since your laptop is over eight years old—replacing the motherboard might be the best option. You can test each possibility one at a time until you identify the cause.
It seems like a RAM problem similar to what the user mentioned. Consider switching to another model with comparable or faster performance and see if any signs of activity appear, possibly due to memory issues.
