battery draining quickly on laptop


bruinator

Recommended Posts

i have a asus x550za laptop which i hardly use. it is about 1.5 yrs old. I keep it charged at all times. When i disconnected it from the charger today it lasted less than 2 hrs before it needed again. According to asus it should last between 5 to 7 hrs. Why is the battery draining so quickly and what can i do to fix it?

 

thx

Must be a dying  battery. If. you charged it 300 cycles,  it will be near the end of its life..

Or you have software that are battery eaters...

Batteries in laptops drain quickly for various reasons...

 

1. what your doing on the laptop... listening to saying mp3's compared to watching a high resolution movie... mp3's battery would last a long time... watching a movie it would last about 1/3 of the time... playing games highend would also cause this...

 

2. use of the laptop... ie constant plugging it in to recharge the battery when its still above a certain percent.. or leaving it plugged in and fully charged.. when you could actually remove the battery whilst its plugged into the mains and used via the mains, only plugging in the battery when you need it portable or if theres a power outtage and you need to do something..

causes the memory effect in Ni'cds.. not nihms.

it is actually a good idea to let the battery drain and then fully recharge it.. which keeps the battery healthy...

example would be my brothers laptop for which he has had the same battery for years... 3 years i believe, maybe 4.

Here is some advice according to the four sources I've read up on the subject.

You should never let your battery drain completely. Doing that uses up one of its finite discharge cycles. Experts agree that you should ideally stop charging your battery at 80%

And, still ideally, charge it when it has 40% of its power left.

Quote

Cadex Electronics CEO Isidor Buchmann told WIRED that ideally everyone would charge their batteries to 80 percent then let them drain to about 40 percent. This will prolong the life of your battery — in some cases by as much as four times. The reason is that each cell in a lithium-polymer battery is charged to a voltage level. The higher the charge percentage, the higher the voltage level. The more voltage a cell has to store, the more stress it’s put under. That stress leads to fewer discharge cycles. For example, Battery University states that a battery charged to 100 percent will have only 300-500 discharge cycles, while a battery charged to 70 percent will get 1,200-2,000 discharge cycles.

Some said that letting a laptop plugged in should be of no consequence since batteries stop charging when at 100% and power is used solely to feed the laptop. Cadex Electronics (in the above quote) disagrees with this.

There is a consensus that heat contributes to shorten battery life.

For your immediate problem I would go in Power Options and customize your laptops power usage. Setting a minimum/maximum percentage usage for the CPU, choosing a power saving option for your wireless adapter, turning off the HDD after "x" minutes, hibernating your system when not in use and shutting off the display after a while when you plan on taking a break...

After having the laptop for 1.5 yrs and hardly use it, I find this unacceptable. What would you guys do?  Asus gave me a ballpark figure of $330 just to look at it and I told the guy that is crazy. Ideas plz?

 

thx

didn't you extended the warranty period earlier? also i would have replaced the old battery with a new one.

So you guys think this is a battery needing a replacement for sure? This is the only laptop i have ever bought or used.

instead of spending 330$ for the laptop check which you won't be doing,i would have ordered a brand new battery.....

When you said, it worked for 2 h before new charging, then the battery is completely normal. 
Power scope is about 70% of the original, and it is also absolutely normal.
You can buy new and get a few more minutes longer use, that's all (of course, under the same conditions).
Buy and try. Lithium-ion battery isn't so expensive. Your original battery capacity is 44W/h, but always may use batteries higher capacity.
 


But if you are buying, look at the time when it was made. For these batteries do not have matter whether they work or they are in stock. Ageing goes in almost the same way. It is about 300 charging or 1 year in stock, it is the same.

Don't know, it is necessary to look at the offers. I bought myself the battery about two years ago. But as I said, if it is cheap, see release date, it is very important.

The release date of the replacement battery?

No, when the content is made, but usually the trusted resellers don't sell old products.

You can calculate in this way, the capacitance of the first year will fall about 20%, ie if new is 44 W/h, if passes year is left about 34 W/h, if two years is gone, is left about 25 W/h etc. 

It is why the release date is important. Usually the components date is nearly the same which is whole battery release date.

You need to remove it from your laptop, look at the model number of it and then search for it's price online and such.

that is exactly what i had done for my old dell laptop......after searching online for the prices i asked my hardware mechanic to get me the battery in the same price range that i found on amazon.....i got my battery with a 6 month warranty along with a proper invoice from the vendor.
