Hello, my laptop is not powering on since today suddenly.

Issue -
1. Pressing power key on keyboard doesn't do anything at all.
2. Connecting charger shows blue light which means battery is full.

Steps I've already done -
1. Battery reset.
2. Pressing power button with other keys.
3. Disconnecting battery from motherboard.
4. Disconnecting cmos battery from motherboard.

Any help would be greatly appreciated.

    Remove the charger. Disconnect the battery pack again. Remove the coin cell. Wait about 8 hrs. Then put everything back. Try to turn it on again after the charge light turns blue again. Jack E/NJ

    How could you have tried this so fast? It's only been an hour? Or did you try this before? Jack E/NJ

    At this point, you must check the KB power button connection to the mainboard. Also check all cable connections to the mainboard. Some but not all mainboards might've been equipped with another spring-loaded safety interlock switch (SWG1) similar to the battery reset switch (SWG2)  The purpose of the interlock is to cut mainboard power if a cover is removed, misaligned or otherwise not pressing hard enough against the switch to keep the mainboard powered. Check around the periphery of the RAM module socket to see if SWG1 exists. Jack E/NJ
