Hello everybody, I have a dell inspiron 15 3542 (i7 4510U, 8gb ram, 1tb HDD w/ ssd cache, 2gb nvidia gpu) the problem is that a few months ago its battery died and it doesn't detected it anymore which in itself is not a problem for me since I use it as a pc.
But I've noticed that a few months ago it slowed down a lot, opening up task manager showed that the cpu was stuck at 0. 76Ghz and no matter what task i ran it would stay at that speed and lag. I tried updating the bios (currently on the latest version) and changing the processor state in power settings to 100% too but there's been no difference, I know that the cpu is locked so I can't manually change the clock rate. Also after the battery died everytime I switch on my laptop before booting up, the laptop gives me this message on a black background saying
"AC power adapter wattage and type cannot be determined. The battery may not charge. The system will adjust the performance to match the power available. Please connect a Dell 65W ac adapter or greater for the best system performance"
I've only ever used the charger that came in the box with the laptop so I don't get it. I know this laptop is pretty outdated by recent standards but I just used to play war thunder on low on it and do homework I can't figure out what is wrong with it. I can't buy a new laptop or battery/charger because I had to save a lot to get this in the first place. Please do help.
