If the laptop does not turn on at all, it would usually be an issue with the motherboard and it needs to be replaced. You may, however, attempt to try disconnect the hard disk, CD/DVD drive, RAM and battery and try to turn it on just using the ac adapter. If there is still no indication of power, you would have to get the motherboard replaced.

Could be a bad battery and/or charger/AC Adaptor/DC Connector. Try to isolate the problem by removing the battery and then plugging the laptop charger in and starting the pc up. It should boot on the AC adapter alone. If it won't boot on the AC adaptor or it flickers and flashes while on the AC adaptor, I would first suspect the AC adaptor or the DC connector on the laptop (try wiggling the power plug at the PC to try and check the connector). If it behaves while on the AC adaptor without the battery present, I would suspect the battery. Either way, you may have to replace something.

My acer extensa 5220 wont accept power from its adoptor


Does the battery charge? Has the AC jack been damaged? Have you verified, with a multimeter, there is no voltage coming out of the AC cord/charger?

My acer 5920 wont charge or wont work on ac adaptor but the ac adaptor works fine on my friends laptop


Either the AC port on the back of your laptop has a lose connection - if operation without battery is an issue, or if battery charge only is issue - then battery may have to be reseated or it is at end of life. Test by removing battery and running AC alone. if connection port is bad, laptop will power off immediately/unexpectedly. Good luck! btw - batteries for this unit are around $40 on ebay

I cannot get my acer aspire 4315 to AC power up. new batteries are ok. i have changed the power jack but no difference. please help


Check the light on the AC adaptor when plugged in to the laptop. If it is flashing, it indicates that the power is being "spat back". That is, not completing the circuit. Means that you have a fault in the charging circuit. I'd check for burning around the contacts where the DC port was soldered onto the board / or if the plug type, check the socket on the mobo is not damaged and is firmly soldered on.

After that, (if not already done) check the output voltage of the adaptor with a multimeter, might be a simple failure of the ac adaptor, even though it looks ok

It could be an AC adaptor issue.

It should boot when connected directly to the power outlet through the laptop adaptor. If it is not boot, then the adaptor might not be supplying the needed power to boot it up.

If it is possible, try to isolate the issue. Charge your new battery using another laptop. Then plug it in your laptop to see if it works. If it will work, then it is the AC adaptor of your laptop that is defective. If the charged battery still won't make the laptop boot, then there is something wrong with your laptop hardware. If could be a motherboard issue of your laptop.

Ferrari 4000 laptop a/c adaptor will not charge laptop,adaptor ok


Hi

Thank you for your query it sounds like you have multiple hardware issues

1) you mention that the ac adapter does not charge, then you say ac adapter ok. Please clarify if the adapter is faulty or the battery

2) As for the line in your screen, your LCD is faulty and will need to be replaced

I would recommend that you book the laptop into a reputable PC shop for further investigation/repair

If this has been useful please leave postive feedback/vote/testimonial - Thank You Again

Says plugged in not charging


Take out the battery and make sure you can turn on the laptop with just the AC Adaptor hooked up.

If you can then you know the AC Adaptor is good. Try another known good working battery in the laptop, if the battery charges then you know that the old battery is bad.

If the laptop doesn't charge with a know working battery or a new one then you know that the motherboard is bad.
