Dell Inspiron 1545 mobo not powering up

[mukisa23]

I recently hibernated my dell inspiron 1545 laptop and the following morning it would not power up. I tried with the battery alone still nothing. Even with the power adapter still it would not power up. What should i do?

It may have nothing to do with the hibernation.
Check your power socket very carefully... The socket has been breaking away on some models... This is a "flat soldered" device, and when it breaks awayf from the motherboard, the board and other components cannot get power.
This requires a re-soldering by a person who is expert in flat solder techniques... it is not a job for first timers.
Whatever the problem, you would likely benefit from having it tested by a shop or technician who has all the right tools for testing circuits, power input, and power output.
It could also be a fusable resister or other device.
Plan to spend some money... Diagnostic time from an expert can be expensive.
