Hi, my LT has suddenly stopped working with no sign of any power at all. I have tried a known good battery and AC adaptor but still no change. I have tried the AC adapter without the battery and no joy. Anu suggestions?

Press the power button momentarily to check if it is hibernating or in stand by. If this doesn't work;
Try firstly removing the laptop's
battery as it may be at a critical voltage and the system will not
start because of it. Plug in your ac adaptor and monitor what
happens. Does the power light illuminate? If it does it should then
boot up, if it doesn't, try a known good ac adaptor before going any
further. If the adaptor is fine and the laptop still won't start,
then you may have a mother board fault and should contact a
dealer/repairer for further advice. Hope this helps.
try to take out the battery and disconnect the AC adapter. Press and hold down the power button for approx 10 to 15 seconds to discharge any power left to it. Wait for about a minute, reconnect the battery and AC adapter and try to turn it on. If it powers and but does not boot to the OS, try to tap F12 key a few times when it restarts and from the One Time Boot Menu, select Last Known-Good Configuration and press Enter. HOpe this helps.
Hi Take the battery out and put the unit on the AC charger and try to start. If it starts your battery is bad. If it does not start then an IC has come away from the mother board. A reputable service tech will have a float device to reheat *********** board and resolder all the IC's
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.
Hi Steve, If you haven't gotten any batteries to work properly at all and the problems are different each time, I would say the motherboard is shorting out the batteries and causing weird problems. One last thing to try if possible..
Try a known good working battery, if that battery doesn't work then its verified that the motherboard is bad. If the known good working battery works in that laptop then you got a bad batch and it will be a battery problem.
Since your laptop turns on with the ac adaptor means that the ac adaptor is good.
Although symptom is showing that AC Adaptor is not working as its not providing power to the unit. I will suggest you to perform some basic troubleshooting steps. Check if outlet is working if not check with known working outlet. If you have a multimeter you can the output of the AC adaptor.
Also you can perform full power cycle and component discharge. Take the battery out and disconnect the AC adaptor press the power button and hold about 7 seconds. After that put the AC adaptor in and test again.
If issue persist take to nearest Service center check with known working AC adaptor. After that I believe you will figure out the best solution.
