Hello everyone,
A friend managed to get an old Latitude E5570 for cheap but it had a completely dead battery and missing power adapter. I'm trying to fix it as a challenge, so I got a new battery replacement, an (allegedly) OEM charger and a new CMOS battery (just in case).
Replacing the battery I immediately managed to power on the laptop and install Windows, but from the bios I can see that neither the battery nor the AC adapter are being recognised. The battery is an aftermarket one, while the AC adapter has the dell logo on it and was sold as genuine from [link|https://www.thelaptoppowersupplyshop.co.uk/laptop-charger-dell-450-19041|here|new_window=true], although the laptop still doesn't recognise them.
Looking around I read that a bios update should fix the issue, so I installed the latest bios from the Dell website. I had to use the /forceit command to install it because it didn't like the lack of AC adapter.
The error I get from the bios is "an installed battery is not identifiable [...]" and then it goes on saying that it refuses to charge it. The battery is now slowly discharging and I'm afraid I won't be able to do anything on it anymore, once it's completely dead. I tried to power on the laptop without battery connected, but I only managed to get it to start up once and never again, I don't understand why. I also tried to do the reset procedure where you unplug battery and CMOS battery, hold power button, plug in CMOS battery and plug in AC adapter, but that only seems to work once too.
How do I get this laptop to charge properly with its new battery? Thanks!
