Hi all, I managed to isolate the issue due to the amount of light blinks if any you see when you first try and turn the laptop on. I have a Dell XPS that has the exact same problem noted above, not sure if HP machines do to the same to help with diagnostics however my machine beeped or flashed a small light where the usual HDD & PWR indicator lights are usually found, 5 times from memory, 3 long and 2 short….something like that. When I checked further into Dell trouble shooting, the beeps translated into a CPU issue, which unfortunately it did turn out to be….hope this helps

Hey everyone, I was actually one of the original people to post a question about issues with the SIM tray not seating properly and whilst I did end up finding out why, I thought I would share my experience and include it with the mix of all the excellent responses that have already been posted. It was hard finding a lot of info online about it initially for some reason and what I experienced also needs to be considered. I repair phones, computers etc and despite checking the inside of the SIM tray a dozen times, I could not find any reason why the sim tray would not slide into the SIM slot. Even with a decent magnifier I couldn’t see any obstructions and it wasn’t until I removed the metal sheath of the SIM reader which also holds the eject mechanism and sim to the motherboard, that I found the tiniest of shrapnel or what looked like small bits of a broken plastic SIM adaptor. Looks like someone has used a broken SIM tray or perhaps at one point, tried to put a SIM into it without using a tray, breaking it...
