Hi just wondering if anyone is good with repairing laptops. I have a Fujitsu Siemens laptop. I wiped it about 2 weeks ago and did a fresh install of windows but about 3 days ago I turned the laptop on and I would just get a black screen then it turns off after 15 seconds. Btw I haven't used a battery in years so it's just been running off the power lead. I was thinking off maybe to just buy a new battery and try that in it?.
