Hi people! My laptop(HP 2230s) will only boot when AC is connected(battery is dead and will not charge when AC is connected and laptop not powered on) In bios the laptop has got no problems @ all but when windows vista starts to boot either save mode or not it freezes! The weird thing is than when i disconnect the AC for a while it continues booting. (battery is propably charged a bit) But i can only do this for 2 sec @ MAX before battery dies. I can boot windows by connecting and disconnecting the AC continually.... But thats idiotic, the battery does not charge more than enhough for a few secconds (i guess it only charges when it is still in bios.) And with AC connected windows is frozen completely. Thats the story. I asume it's not the AC/PS because it works fine in bios/before OS starts or begins to boot. The laptop has got some fancy increadibly user unfriendly interface which allows you to use your mouse... Anyway i can run several system diagnostics. Most of them freeze when they are checking Memory. sometimes at 17 % some times 47%. But what is most intresting is that the HDD check, runs and completes and says that it failed. (without explaination) Whats the best course of action? I want to try to instal an other OS, but i would really apreciate it if i can BACK up my files or somehow get them on an Exteral HDD. Many thanks!
