Laptop still won't turn on, adapter is good, no green light on laptop.

Does the HD light turns on?
If not, try to open HD bay, disconnect and reconnect disk.

Hello, If the battery won't charge and the laptop won't turn on but the ac adapter works with other laptops, then the problem is the port where you plugin the ac adapter. Some of the laptops has it built in to the motherboard. So you might need to have it repaired by a technician. Or if the laptop is still in warranty, you might need to send it to the manufacturer to have it repaired or replaced. But if the laptop works without the battery, or it will turn on but the battery indicator is not lighting up, you're facing one of these problems. 1. The battery itself is dead. 2. the battery bay is loose 3. the battery itself is loose Hope this helps

CHECK CMOS BATTERY ON MOTHERBOARD...MAY BE DEAD
GOOD LUCK

First, you need to make sure your power adapter is providing enough power to both run the laptop & charge the battery. A very good way to do this is to compare your laptop voltage & ampere requirements (written on a sticker on the bottom of the laptop) with the voltage & ampere ratings of the power adapter. Voltages should be the same, or the power adapter's voltage about up to 0.5 volts more than the laptop's voltage rating. Amperage of the power adapter should be at least equal to or greater than the laptop's rating. It should never be less than the laptop's rating, or else the power adapter will be providing insufficient amperes to charge the battery. Of course, the power adapter's nominal amperage might be ok, but it degraded on usage. You can verify this by testing using a good or new power adapter.
If the battery did not charge using the new power adapter, take the battery off the laptop, & using a dry tooth brush, scrub in between the fins of the battery connector on the motherboard & on the battery it self, then put the battery back into the laptop & try again.
If this still did not resolve the problem, then the battery itself could be bad. Try it on another laptop, or try a good or new battery in your laptop.
If this did not work, there might be a possibility that the charging circuitry on the laptop's motherboard is defective & needs servicing. In order to do this, the laptop needs to be disassembled & the motherboard checked for defective/burned out components in the area near the DC jack. Any defective/burned out components found should be replaced, or you might need to replace the laptop's motherboard altogether.

There could be a problem with the battery. A fast check to determine whether you have a problem with the power adapter, power cord or the laptop's battery is to turn off the laptop, remove the battery, connect the power adapter, turn on the laptop & see if it works.
If the laptop works directly from the power adapter with the battery removed, then the power adapter is good. In this case we can suspect that the battery is defective & needs to be replaced.

If this did not work, try also disassembling the laptop & make sure that all main components are seated properly. Also make sure that all ribbon cables interconnecting the various components of the laptop are tightly connected.

which green light?

light from the ac power adapter or the light from the battery?

if ac power adapter you are referring to try a diff power wall socket if ac power adapter still off then replace ac power adapter alone.

if battery light is off but the laptop works fine with ac adapter alone try updating the laptop BIOS.

if ac adapter light turns off when it plug to the laptop replace motherboard.

try connecting ac adapter alone without the laptop, check if ac adapter light will stay green or blue.
try another power outlet using the ac adapter alone without the laptop check if the ac adapter light will stay as green or blue. if all fails replace ac adapter.

if ac adapter stays green or blue try connecting to the laptop without the batt, check if the ac adapter light will stay on, if yes then try connecting ac adapter to laptop with the batt plugin check if the light stays green. if not update the BIOS. if fails replace motherboard.

Leave the battery disconnected and only hook up the ac adapter. See if you can get the laptop to turn on and get video. If you can then that means either the battery is bad or the charge is so low on the battery it can't turn on the laptop. If the battery is bad then you would have to replace it.

If you still can't get the power on then check the ac adapter to make sure the green light is on. This will let you know the AC Adapter is working properly. if the light is on then the adapter is good, if the green light is not on the adapter then its bad and would need to be replaced.

If after these steps you still can't get power to the laptop then that means the motherboard is bad and would need to be replaced.
