Hello, I have an ancient Sony Vaio laptop (PCG-7Y2L) that refuses to post. It doesn’t have a battery and nor do I intend to spend 115$ on eBay for a new battery. No, 115$ is not a typo. However, I’m afraid the lack of battery might be why it’s not posting. All that happens when I hit the power button is This: Upon pressing the power button, the laptop’s battery light will come on for as long as the power button is held, then the HDD light flashes for a quick second, and the DVD drive initializes, after that the caps lock, num lock, and scroll lock LEDs all light up and never turn back off, the CPU fan never spins up and there’s never an image on the screen. It’s like it’s just about to post, but then it just decides it doesn’t want to exist. Is this a bad CMOS? I know they’re rechargeable Nickelmetal hydride batteries, but idk if those going bad will affect its ability to post. I think the problem may be the main battery though, as I’ve heard Sony laptops are stupidly finicky about batteries, but what do you guys think? I’d like to get this absolute unit of a laptop working to have an old XP machine.
