Calibrate the battery every 2-4 weeks. In terms of cycles, I have no idea.

You can't do that on some laptops. I can't on the Y500 too.

Lenovo and HP dont allow speedfan manual control
Dell and Sony do
One workaround is to flash a custom bios but thats risky,rare and voids warranty or may even permanently damage the laptop

custom bios can but its very very risky imho and is probably best left alone

If you knew how old my laptop is, you'd wonder how its still alive and working good.

On-topic: where can I find such custom BIOS?

Hello guys, I am looking for a thermal paste for my Dell Inspiron 15R. I am thinking about Arctic MX-4 but where can i get this online or offline in New Delhi? What about Arctic silver 5? Is AS5 better than MX4 ?

I am on a custom bios for overclocking but still can't control fan speed. I think Lenovo disables that.

I dunno about Lenovo but for some laptops,custom bios might revive fan control
you can see the changelog of custom bios threads incase someone found a way

EDIT- I just checked some other forums,Lenovos dust removal option in Lenovo Energy enables fans to run on 100

Lenovo R61

Tried to replace the thermal paste on dad's Dell N5110, 2 of the screws which keep heatsink attached to the mobo didn't even budge.

They are supposed to be tight to apply maximum pressure unto the core for best contact.

Yep that is the only way to make it run at 100%. However, it has been speculated that running it at 100% all the time might damage the fans.

Yep thats true!

charging and then using on the battery will lead to wastage of battery cycles. It is better to use the laptop always on ac power with the setting(50-60/70-90) on.

my 8 year old Vaio hasnt conked off,never even had to get it serviced

- - - Updated - - -

once the battery reaches 100 on any laptop,itll automatically switch to AC Power and not use the battery at all
if you have desktop charge etc on,itll maintain it at 99-100 by charge and discharge
Theres no way of frying a laptop battery by overcharging
the charging cycles thing is only if you regularly discharge to absolute 0 and charge to 100 ie a full cycle every day-thus increasing battery wear
the battery can be affected by heat however ie while gaming etc

By conking off I didn't mean over charging or overheating. Of course it won't "over charge". I just meant going bad.

This is what I saw in some of the laptops, especially in Dell laptops. There was one friend, who didn't use his battery single second, and his battery went from 4 hours to 4 sec in less than a year.

I might be wrong, but I just shared what I observed in day to day experience.

Dell batteries are naturally bad. My laptop was overcharged in the official store for like 1 day and it showed wear at 10%. I got the battery replaced on the spot.

Yeah Dell batteries wear out pretty fast but overcharging etc isnt the cause
apparently two manufacturers make dell batteries,one is the stock one we get in India,the other is obtained from abroad or if you RMA your battery at the service centre
the stock one is pathetic,I have 23% wear in just 2.5 years whereas my 8 year old vaio still has 18% and my 2 year old HP G6 has 0%
Dell really needs to do some quality control in Indian models for its displays and batteries

yeah but its not because of overcharging
Dell uses poor quality batteries in India,if you RMA them,you get better quality ones made by another brand

 

[dashing.sujay]

One more thing I'd like to say that battery wear should be taken with a pinch of salt as it does not shows the whole story.

Say if a laptop has got 0% wear, so technically that should also be giving 100% back up of its capacity, but it does not.

That means [MENTION=184724]kkn13[/MENTION],as according to your usage + experience,DELL Batteries are a crap.
In that case,when do I RMA to DELL for a battery change???

yep plus even the wear itself will always fluctuate all the time ive noticed
mine has gone upto 35% once and come back to 20% after a full recalibration and another recalibration later 18%

Yeah atleast on my laptop model and gen/series - 3rd gen ivy bridge based inspirons which are notorious for this
but its only if you got the bad manufacture batteries - Sanyo i think
the RMA one is Simplo

EDIT- Heres the thread where I learned of this
*www.digit.in/forum/laptops-netbooks/158133-dell-inspiron-14r-15r-17r-turbo-laptop-thread-309.html

I didnt take an RMA one as I was out of warranty when it reached alarming levels now its constant at 30% again and I usually use it on AC only so battery isnt that big a concern for me as long as I get 2hrs battery life when in college etc

[MENTION=184724]kkn13[/MENTION],when do and how do I callibrate/recallibrate the laptop battery?

the simplest is a full recharge and full discharge
though it shouldnt be done too often otherwise itll harm the battery instead of the opposite

I did it yesterday night. Completely discharged my laptop's battery to 0% through continuous usage and monitoring through the battery care tool,till it shutdown completely. Later with immediate effect I recharged it fully to 100%,while I was asleep whole of night.
