    Hi there,

    So I have been having this problem for the past year or so, where upon pressing the power button, it would turn on for 2-3 seconds, then turn off, power on 2-3 seconds, then power off, and it does this repeatedly anywhere from 45 minutes upwards of 2 hours. All I get is a black screen for the short time it's powered on, so I can't even get into the Bios.

    So far, I have tried different hard drives, taking out both sticks of RAM and trying different slots individually, disconnecting the Cmos battery, and nothing has worked. I don't know what else to try at this point, and with prices of any PCs / Laptops at this current time, I can't afford a new one.

    If anyone can offer any solutions as to what the issue might be, it would be immensely appreciated. I flashed the latest Premamod a while back, and it worked perfectly for years before this issue suddenly appeared out of nowhere.

    Thanks in advance!

    Could be detecting a short and shutting down or a bad connection like a solder joint. Does it do it both on AC and battery? Does the power brick have an LED? Is it out after the machine has tripped?

    Well, the battery is completely dead (holds a charge for maybe 3 seconds, then shuts down if not on AC). It does this tripping while on AC too though. The power brick does have an LED, and it doesn't shut off at all when it trips. Not sure what else to do at this point...

    Next step would be to remove the GPU and see if does the same thing. If it does improve the situation the machine should beep at you and shutdown but get further than you are.

    I took out the GPU tonight and gave it another go, and unfortunately it's doing the exact same thing. I'm basically at a loss now without any other ideas to try. so if you have anything else to suggest, I'm completely open to anything at this point.

    There is a slight chance the IMC on the CPU is having issues but that's super hard to test without a spare chip.

    So what you're saying Is my laptop is basically dead because I imagine a 4th Gen i7 would be super hard to find and outrageously priced in this current market.

    Have you checked eBay and the like? Usually not too hard to find. It's a specialty part.

    Yes I've looked at typical online stores such as eBay and the like, but at over $200, is it really worth it for a CPU that is 6-7 generations old? I would be pretty mad if I bought one and that turned out to not even be the problem, especially considering the CPU wouldn't be returnable.

    Do you happen to know of any other things that could possibly be the culprit before even considering buying an old, used cpu?

    You could remove the motherboard from the case and go to real barebone.
