So i upgraded my hp laptop from 500gb hdd to 500 gb ssd and increased from 4 to 12 gb ram. When i did this my laptop was more than a year old. About 4 months later my battery died so i bought a replacement battery according to my model no. and serial no. but i didnt account for increase in specs the replacement was working fine until 6 months later which is now it suddenly started draining my battery in 15 minutes. I dont know why it suddenly started draining. can anyone help me out.
