    Laptop charging

    I have been doing a clear out at home and found an old Sony Vaio that I thought of re-using either as a small server or as storage. The laptop always had a few problems after a young child accidently tripped over it, I suspect it was hardware. However this laptop has been sitting in a bag, untouched for about 3 years and I thought I would charge it up and get it networked, here is the problem.....it won't even boot up, not a squeak or movement from the fan, ziltch.

    Can this be caused by a flat motherboard battery? How long should I charge a battery after it has been switched off for such a long time?

    Jerry,
    I think it depends on the type of battery pack is in the laptop. The older type batteries could develop "low voltage memory" and would never recharge over a certain voltage, no matter how long you leave it on charge.
    I don't know if your particular battery iswas of this type or not but it sounds like it is. There was a "trick" to blowing away this memory by hitting the pack with a MOMENTARY hit of over-voltage when it is disconnected from the laptop but I'm not sure I would recommend this without knowing exact the type of battery.

    Hi Bob,

    The charge light isn't even on now but the battery is a Li-ion or Lithium Ion 14.8 V/4000mAh

    Jerry,

    OK, if it'a a Lithium, then all signals off.
    They didn't have the memory problem.
    Do you have a volt meter to quickly check the state of the batteries? Anything showing a few volts under the rating is not good news.

    I have an old Advent laptop that I could only get to work 'reliably' by removing the laptop battery entirely and always running it from the mains adapter...

    Batcher beat me to the punch. <img src=/S/grin.gif border=0 alt=grin width=15 height=15>

    I've had three laptops over the years, 2 Dells and 1 IBM. All three were able to run without the battery installed when connected directly to wall power.

    I would imagine that if you you wanted to use it as a small server then battery power wouldn't / shouldn't be an issue.

    Sadly, with the battery out, I still get the same problem, no boot up, no catch, nuffink <img src=/S/sad.gif border=0 alt=sad width=15 height=15>

    I have a feeling this is going off to the great laptop landfill site in the sky.

    Re: Laptop charging

    The last option before ditching might be trying to source a new CMOS battery.

    I just used Google to search for sony vaio cmos battery and it brought up many hits. Some suggest it might be difficult since some units have the battery soldered. While others have comments about some units having expensive batteries while others have prices around US$10.

    If your's takes a US$10 battery and is easily accessible, it might be worth the investment.
