hello!
since yesterday i've had this peculiar problem. when on and plugged in, it would say "plugged in, not charging" and constantly switch to "plugged in, charging"(rarely) or "not plugged in". this constant changing would take place every few seconds and the beep-ing would drive me mad(if sound is on).
also, the battery discharges as if it was running only on battery power.
if i remove the charger, the computer runs without any problems on battery power alone.
if i shut it down and plug in the charger, it would charge the battery normally.
if i remove the battery and attempt to boot on adaptor power alone, it would start but only run for 1-2-3 seconds than shut down.
this is obviously not a battery issue since on battery alone it runs flawlessly. on various other troubleshooting sites i've found that it might be a issue with "microsoft acpi compliant control method battery" however i tried uninstalling, updating drivers and a few other unlikely methods to no avail.
my best guess is that either the adaptor cable or adaptor itself got damaged somehow and it's not providing enough power to run the laptop (however enough to charge the battery when system is shut down). i have no way of testing it though.. the only solution is to buy a new adaptor and hope this was the problem indeed.
my second best guess is that the laptop's inner power circuit got messed up (this would be rather sad as depending on the damage repairs could cost me as much as the laptop itself 
... ). is there any way i can test if this is the case? any diagnostics program or somesuch?
any other ideas or feedback are welcome. cheers!
