It's really confusing. When plugged in, everything is lagging. On battery everything goes smooth, three times as fast.
I looked into power options, set everything to default and tried the three modes: power saver, balanced and performance.
What could be the problem?
Specs:
Dell Inspiron N7110
Intel(R) Core(TM) i7-2670QM CPU @ 2.2GHz (8CPUs) / 8 GB RAM
Windows 8 Pro 64-bits
EDIT 1: After a little investigation, I noticed that the needed energy for my laptop is 130W and my charger only provides 90W. I don't think this is where the issue is because the problem did not arise when I bought this charger but way later.
Is there a way to better manage my power settings? Or at least some way to use both the charger and battery at the same time and decrease battery consumption.
EDIT 2: It seems my problem arises if I unplug the power cord and put it back.
1Is there more than 1 power management software installed? Or any settings in the BIOS for this? – Dave – 2013-09-12T11:27:08.347
No, I didn't install any power management software. As for BIOS settings, I didn't change anything. – Wajih Aziza – 2013-09-12T11:37:00.343
2I meant did any come pre-installed. In regards to BIOS settings, you said you didn't change anything which indicates this is a new issue? – Dave – 2013-09-12T11:49:48.643
It is new, also I installed windows 8 and the drivers myself. – Wajih Aziza – 2013-09-12T14:38:22.867
