New battery - Laptop going slooooow
Bought a new battery (P53IN4) for my laptop (Rock - Pegasus 665).
Battery charges ok to 100% but when I disconnect from the mains, the laptop seems to slow right down :mad: Never did it on the old battery :wonder: Is the new battery a dud? |
Might not be powerful enough or the power settings could have it running at lowest performance.
Right click desk top, properties, screensaver, power options.. I think |
Agree on power settings. If your previous battery was dud and you only ran it on mains you may find the power settings on battery saver rather than performance.
|
Power settings haven't and don't change between the two batteries. :(
Power output details on batteries are the same on both. i.e. Li-ion 10.8V 4400mAh Looks like the new one might be a dud! :rolleyes: |
What people are suggesting is that the device runs the CPU at a far slower speed either when on (all) battery power, or specifically only with this battery.
It is going to be something of this sort causing your problem because PCs either work or they dont. They run at full speed (saying this might be confusing), or they dont run at all; but they wont ever run less quickly as a result of problems. A computer will run at full speed until it dies, its the operating system that runs on it, and the applications that run on the operating system, that slow down as they become 'un-optimised'. If the machine cripples the CPU speed when the battery power is running low then this might indicate that the new battery is at fault. If the battery proves t be good then it will almost certainly be a configuration issue. |
What I did notice is, with the "original" battery, with a couple of programs running the CPU usage is at around 4-5% when "idling" climbing slightly when I start moving the mouse etc.
With the "new" battery it idles at about 40% :eek: then as soon as I start doing anything it jumps to 60% + even up to 80%!! |
Did you get this fixed? I am having the same problems and I have been through 3 batteries.

Afraid not, I gave up in the end. :( Put the original battery back in and just run it off the mains all the time........and then bought an iPad which made my laptop pretty redundant other than syncing iTunes anyway. :lol1:
I think it was down to the "new" battery being a dud (cheap Chinese copy :rolleyes: ) I tried to save some money and get one from eBay rather than getting a "proper one" but after sending it back at my own cost and receiving another one it did exactly the same thing. I think the only thing to do would be bite the bullet and pay top dollar for a genuine one but as I use my iPad all the time and I'm thinking of getting a Mac for the whole family to use I don't really see the point. Sorry I couldn't be any help. :( |
Both of these problems can only be down to Power Options / Power Schemes - as has been stated before batteries either supply power or they don't...

The link doesn't seem to work for me, just brings up a blank page. (scrap that, working now)
Regarding the power options, am I missing something? I go into the power options window and with either batteries installed the settings are the same. They don't change with either battery installed, but the CPU usage goes from 4-5% at idle with the original battery and jumps to 40% at idle when I change battery. The power settings are still the same though. :wonder: Is there somewhere else that I can look to check power options? |

The 'OEM' one was also generic - nothing special. Able to change the CPU speed at will by chaning the battery only - and I have been though three batteries from different companies. DrT |
So which "Power Scheme" is your machine using when on battery, and which is it using when on AC power?
|
It's set to portable/Laptop

@Dr NO
1) the power settings do not change when the battery does 2) Power settings changed to 100% CPU at all times WITHOUT effect 3) Two distros of linux on same PC affected by this issue. The issue is NOT related to one OS's power settings...QED. If everything is constant apart from the battery, how can you believe otherwise? DrT |
Just a thought, run CPU-Z when on power & then again on battery.
http://www.cpuid.com/softwares/cpu-z...s-history.html It might show a different multiplier or clock speed. |
Hi,
I used HWinfo32. I do not have the battery to test any more but all three showed a reduction in CPU/FSB speeds. The original battery was nothing special and the three replacements that I tried were of all different manufacturer. They are quite common when one finds out the other laptops that used the same chassis. OT - When I lived abroad for a while, I had a Subaru 700. A 5 seater 5 door car with a two cylinder 700cc engine that was a brilliant runner and a mini-killer. Cheers DrT |
I know with our Dell Vostro in the workshop; if it detects a non genuine battery or power supply it comes up with a pop up message saying speed maybe affected.
Its also telling us the genuine battery is 'worn out' even when used solely on mains. This makes me think there is something hardware wise within the battery and Laptop's BIOS that configures the voltage/cpu speed independantly of the software/OS depending on the power source and if its genuine. I suspect there is a bit of hardwired obselecence and anti-competition built in. Bit like chips within printer cartridges to prevent you using refils...FFS even our Glade Freshmatic air-fresherner has a opto-switch to detect if its using genuine refils :lol1: |
You could very weell be right, except that the original battery is as generic as they come. It is made by Gallopwire and the only recognisable and on it is in the statement that the cells are made by Panasonic.
From the research I have done, this laptop is *identical* to many of its brothers out there and the only mod is the retailers badge placed on the chassis. It is a very fast computer and I can see it having several years of use left (it was bought in about 2003)...just wish I could get a new battery. The original's capacity is less than half the original now. Drt |
