I reveived this laptop dead.
The polarity of charger was inverted and pluged in. The laptop dosent kill instalntlly, but after battery drein (15 min after), laptop shut down, and now dosent power or charge or blink.
I read in internet and more people have same problem in another forum and they suspect "TPS2421-2".
Can someone point me correct direction please? my VIN of u521 dosent have 12v
