[krilas]

Yes I have big problems: I buy used SONY VAIO GRT 815M, by befault it must have Intel® Pentium® 4 2.80 Ghz processor, but my laptop have 3.06Ghz PIV processor, intresting why? Maybe he is refurbished? OK, for processsor I don't thing what this big problem and buy this notebook, but after 3 mounths my battery suddenly dead. Just use laptop from battery, baterry go to end, then plug adapter but it charge until 53% but don't work - if unplug adapter computer shut down in same second.
After some time I buy new battery and original adapter from US, but after 3 weeks happen the same I work with notebook from battery baterry was full, about 89% energy, but computer quick as a flash stop working. Battery again dead. Whats happen? guilty my notebook? What I must doo? How repair?
One more I saw notice - when I work from battery with SONY, it work more slowly - its normal? And the fan work with full speed.
So what can You say? Why so happen for my?
Sorry for my bad english :smileyblush:

Maybe this problem can solve if I put into the laptop slower procesor that 3.06Ghz, maybe this damage my 2 battery? My laptop must have not 3.06Ghz but 2.8Ghz procesor, maybe for this need more energy and my batery die anter 3 weeks 😞
