1328414	2013-02-16 08:49:00	Hi guys, It's been quite a while since I've been here last time, a lot of things have changed I see, but I hope someone will give me constructive reply, like it was in the old days :) I have, among other Dell laptopts, my favorite DELL Vostro 3750 , which is about 2 years old. Guess what happened: from day to day battery decreased itself's performance by about 25%. How do I know that? I checked battery status on Monday - I still had about 2 hrs time to work without AC adaptor. Suddenly, on Tuesday, battery time decreased to 1 hr 30 mins. I'm engineer myself, I know the chemistry of Li-Ion and Li-Poly batteries - these batteries are reliable, can stand up to 10 years, and NEVER decrease their performance by 20% in a second; I also know that there is a chip installed in the battery, that counts charging times. I read on other forums that people revived their batteries using 3rd party software, setting this counter to 0 in the battery EEPROM. Personally, I'm a little bit afraid of using such software especially that is quite expensive. So, how can I reset internal battery counter, so I give battery cells the chance to die in the natural way, not the Dell way, so I just don't replace a good battery only because someone wants to make quick money on me? Constructive replies are really welcome :) P.S. After switching off all power saving stuff, battery is still holding for about 2 hrs, magically staying at 3% :) Anyways, I tried to drain it to zero, remove it, press the button on the battery along with power button on the laptop, but still both BIOS and Dell Battery Power Meter tells me stories about decreasing performance. There simply must be a way to reset this message, as battery cells itself are not intelligent enough to report that they are dying - it is software issue.www.batterietutti.com Help please!	chongqing (17014)

One thing I noticed is when my laptop was new, my battery life was cut by more than 1/2, the 'problem' was a CD in the drive, unessential of course, I wasn't using it. But the laptop was keeping the drive spooled up and thus draining power. I'd hate to question your engineering though, but Li-ion batteries don't last up to 10 years, neither do Li-po's. A good Li po may do 600-1000 charge cycles. Li ions do better but they still degrade per charge cycle. My laptop which is nearly 2x years old now probably gets ~40 mins normal power, maybe an hour or there about with some power saving enabled. Used to get 2 hrs high performance, and 5-6 hours low power. I would agree with some form of conspiracy around batteries, after all, printers have atrocious things going on with their ink!! But I'm also sceptical too, since I know batteries degrade. 2 years old to me sounds like good battery life. I'd consider a replacement battery as opposed to "resetting" the EEPROM with some fancy software. Also, I doubt fancy software on the laptop can do an EEPROM reset. I suspect you would have to short some pins on the board inside the battery. If you go as far as opening it up nicely, you might as well buy replacement cells to rebuild the battery anyway!! Do I smell :spam: ? Seems like you had no luck with your other laptop last year... that makes this one nearly 3x years old? en.community.dell.com	The Error Guy (14052)
