Laptop won't start

HP Recommended

I recently updated my laptop and now when I try to start it up it powers on and the lights come on but uts just a black screen and won't start? Any suggestions?

One zero-cost thing to try: 

1. with the laptop computer powered-off, remove the battery

2. disconnect the power-cord

3. hold-down the on/off button for a few seconds, to drain any "residual" electrical power from the motherboard

4. reconnect the power-cord

5. does any lamp light up to show that the laptop acknowledges that it is receiving AC power?

6. if so, try a power-on

7. if not so, then the battery probably has 0% remaining power -- it previously ran down to that level

8. consider either a dead power adapter, or a broken jack where the power-cord connects, or a dead motherboard.



Good luck!
