Guest Andy Fish Posted October 2, 2007 Posted October 2, 2007 Hi, I have a sony TR5 laptop which is about 3 years old now. Although the battery will last a good 2 hours, the battery meter drops to 0% after about 1/2 that time. That's not a problem in itself - I've seen it on other laptops before. I simply went on to the "alarms" section of the power control panel and made sure that it didn't hibernate when the battery level goes below 3%. I have to suffer the occasional unexpected shutdown when the battery actually runs out but I can live with that. That was fine until I reinstalled windows XP and now the PC always hibernates when it thinks the battery is low i.e. after an hour, regardless of how I configure the low battery alarms. is there something else that is taking priority over these settings. It's a PITA only being able to use 1/2 the battery life of the laptop. TIA Andy
Guest David Webb Posted October 2, 2007 Posted October 2, 2007 Re: stop laptop suspending when battery gets low Check your owner's manual to see if there's a calibration procedure required when you install a new battery. If so, try it using your existing battery. Good luck!

Did you visit the vendor site for sw updates? Driverguide.com? It's not unusual for the vendor (Sony) to overlay a separate power management utility. FWIW, the failure mode of LiION batteries is increased series resistance. The electrons are in there, but the laptop won't let you have them because it thinks the voltage is low (due to series resistance under load). So, your battery is "bad". Yes, the vendors could design around that issue, but then they'd make less money. Some clever dude could make a fortune with a battery utility that was aware of this problem... at least until the bankruptcy due to the first lawsuit they got caught up in through no fault of their own. mike mike -- Return address is VALID!
Guest PA Bear Posted October 2, 2007 Posted October 2, 2007 Re: stop laptop suspending when battery gets low How old is the battery? How long have you been using it? Was it remanufactured/recycled battery or a brand new one? Did you purchase it from Toshiba? Do you leave the battery in the bay even when running on AC power? Do you store the battery at 100% charge? Why did you find it necessary or choose to reinstall Windows? Did you do a Repair Install or format & reinstall? Is the machine fully patched at Windows Update? Are there driver and/or BIOS updates available from the computer manufacturer's website that you've not install yet? -- ~Robear Dyer (PA Bear), working offline MS MVP-Windows (IE, OE, Security, Shell/User) AumHa VSOP & Admin http://aumha.net DTS-L http://dts-l.org/ Andy Fish wrote: > Hi, > > I have a sony TR5 laptop which is about 3 years old now.

Guest Andy Fish Posted October 3, 2007 Posted October 3, 2007 Re: stop laptop suspending when battery gets low thanks for all the responses (and thanks to mike for the explanation) basically I reinstalled because it just seemed to be full of crap and I wanted to clean it out - it runs much faster now so that part of it was a success. Because the dvd drive is broken I could not use the sony recovery DVD so I had to install vanilla windows xp. I reinstalled all the sony drivers and also the sony specific power management, and I've checked on their web site and there are no more updates. I've also done all the windows updates the battery is the original battery that came with the laptop and there aren't instructions on how to recalibrate. I don't particularly want to replace the battery because I know it's good for 2 hours which is fine for me - it's just a PITA not being able to use the last hour of it Andy "PA Bear" <PABearMVP@gmail.com> wrote in message news:OgkODcUBIHA.1168@TK2MSFTNGP02.phx.gbl... > How old is the battery?

Do you store the battery at 100% charge? If the machine and the battery are 3-years-old, I'm afraid it's time for a new battery, Andy. Expect to pay ~$150US. With proper treatment, the usual lifespan of a LIon battery is only 2-3 years. (I just had to replace a 3-year-old one.)

See http://www.batteryuniversity.com/index.htm > for some tips. > -- Rubbish. Properly looked after Li-ion batteries can last 10 years or more. I have several examples that are 14 years old and still give full capacity. The things that cause batteries to fail are: 1. Use. Li-ion batteries only have a (typically) 300-500 cycle charge/discharge life (or 600-1000 half cycle). 2. Lack of use. Leaving batteries unused causes the internal resistance to rise due to oxidation. How quickly this occurs depends on many factors mostly related to the actual construction. But worst of all 3. Heat. Even modest amounts of heat will kill a Li-ion battery. Which is why they should be removed rom a laptop if it is being used on AC power (unless being charged - best done with laptop otherwise off).
