There is a "CMOS" battery on the motherboard, it sounds like it has lost its power.

CMOS maintains certain system settings, such as the date and time when the computer is powered down.

If you power off the computer, open the case and look at the motherboard, you'll see a flat battery that looks like an oversized US Quarter. Get the number off it, go to a local Walgreens or hardware store and buy a replacement. Just put it back in the same position (usually with the "+" up.

You'll have to enter the bios routine (press "DELETE" on boot up, and enter the date and time) the first time you boot after replacing the battery. Look for the "Save Settings and Continue" message on the BIOS configuration screen.

These batteries need to be replaced every 2 - 4 years depending on your luck.

If that doesn't work, please let me know, and we'll explore other ideas. If it does, please mark this question as a "Fixya"

Good Luck,

I cant charge the battery through computer

The C183 isn't a battery charger. If you use rechargeable AA batteries in it, you must charge the batteries outside the camera using a separate battery charger.

Hi i have toshiba p305-s8830 i have new battrey but battrey cant be detected from the computer ?

If the original battery can be detected (even if it no longer holds a meaningful charge), and If the "new" battery is a 3rd party manufacturered one - and most of them are - it (the new one) may very well have been dead to begin with. Now please realize that these notebook batteries are not just a bunch of cells connected or wired together - it's a lot more than that, as there's also a circuit board between the battery contacts and the cells, and this circuit board almost always contain some form of propriety stuff that 3rd party battery manufacturers have to "reverse engineer" to be as close to the original specs as possible, and this reverse engineering stuff ain't always perfected or tested fully.

If I were you, I'd return it, get a replacement, and if the replacement is still not detected, I'd go with some other brand /manufacturer. This kind of stuff happens quite often.

Laptop cant detect discs

Hi, Unfortunalty this is an hardware failure there is nothing you can do. If you are under warranty i suggest you to contact the reseller/manufacturer to get a replacement unit, it should be no problem at all this is a common issue. HDD,batteries,power adapter are the weakiest part of your system and generate the heaviest part of hardware failure on computers.
Thanks and have a nice day J -

The PC seems to be OK. The phone switches off and hence can not be detected. You cant detect a dead device. Try a different battery. Or try using the charger while connectiong. If it does not go off then the battery is at fault. Change it. If nothig is detected faulty, then uninstall PCSuite . Restart the PC and re-install PCSuite without connecting the phone. When you connect the phone afterinstalling the SW, he phone will be detected immediately.

Not detected by pc

Sounds like either your motherboard is failing or your battery is starting to fail. If the battery is shot then the unit will not be able to properly connect with iTunes and will not be detected by iTunes. If you need additional support options or want to recycle that iPod, let me know.
