How to troubleshoot laptop startup problems

When your laptop lights momentarily, but almost immediately shuts down, try removing the battery and booting the unit with the battery removed. If there are any problems with any devices such as the battery, fan, ram, wireless card, dvd or hard drive the unit will not boot. You should also remove the cd, ram, wireless card and the HDD. With those items removed if there are no other problems your unit will boot as far as the BIOS and then prompt with a message saying there is no operating system. This would eliminate the motherboard as the problem. If your unit does not boot to the prompt you have a fan problem or a motherboard problem. At this point you would have to remove the bottom cover and try to boot while watching the fan for movement. No movement, replace fan. Movement, replace motherboard. It it does boot to the prompt try reinstalling the HDD and booting. If it won't boot then the HDD is bad and would need replaced and formated with the original factory discs. If it boots with the HDD, try installing the ram and booting. Same procedure until you find the bad part. This will take some time but should narrow the problem to the bad part.

What is wrong when AC Adapter is beeping continuously, and does not recharge laptop battery?


The adapter's Syscon detects a short circuit. It might be within the adapter itself; or with your system. Contact the authorized service centre in this case. If you have an other adapter, load it with. By this way, you can get an idea about the faulty unit. Electro help
