extended 'no-start' any issues on laptop?

does not booting the laptop for a while could cause any issues? (don't think so, but i will tell the story more below)..

the sony monitor was broken.. when we booted we can see some part of the monitor, others were dark patches as evidence for the damaage... other than that, all other features worked (CD/Audio/Video to S drive, wireless etc). so we thought it was wise to change the monitor and get it going.

so we ordered a new one and came after a delay.. meanhile, without shutting down, we just closed the laptop lid and put it in a corner. By the time the new monitor came, assuming all the battery is gone, we just took off the monitor, and put the new one, and started again.. but now there is no life on the monitor.. we thought it may be the new monitor.. so we took it off and put the old one.. still the same..

the power and batter indicator is on.. but there is no HDD indicator (VGN 220E).. so now wondering somehow if the power supply or motherboard could have damaged when I was turning the laptop around etc.

one mistake is i should have started the laptop to make sure it is working before putting on the new monitor.. now, i don't know if something broke between the time the laptop was in the corner (no one could have touched.. so possibility of physical damage there) and the new monitor was put in..

any thought how i can troubleshoot this?

the laptop is 4 years old and well used. (used in lot of car and air travels)

when the power button is on, the caps lock does not turn green, so i suspect the HDD/OS is not turning on..

anyhow - i would start by removing he battery, and test with AC adapter alone (try also VV)

more steps to try :
here my laptop troubleshooting guide :
- remove all external devices
- if no display - test with an external monitor
- test if it runs from battery alone, or from AC alone
- test also with a known good battery !
***some laptops have a reset button - if you have one use it!
- remove battery and AC adaptor, hold power button for 20 sec, connect AC and reboot --> any display ? if NO -->
- disconnect all disk and cd drives, battery , and other cards and peripherals, leave only 1 ram stick
- boot -->any display ?
- if NO remove all ram and reboot --> if NO beeps, mobo or cpu bad ; if it beeps, replace ram stick
-if you can access the bios battery, remove the battery, AC, and bios battery for a minute to reset the bios
or test it, it should read 3 V
*** you can test the disk on another pc, if you like !

Difficult to tell -as a first step I would suggest to hook up the new monitor to another known good machine and see whether it works. It could be that the old monitor has caused damage to the video card of your laptop and it can not 'drive the ne monitor' . If the new monitor works on another machine you'll know the laptop is at fault - typically the video adapter is part of the motherboard of a laptop and unless you feel comfortable swapping the laptop motherboard yourself - typically cost prohibitive due to high labor and material cost for a motherboard swap.
The laptop might be stuck in hibernation mode.  To fix this, unplug the power adapter and remove the battery for a few seconds, then put the battery back in and plug in the power adapter.  Try the power button.
