[kamran saeed]

i have hp r15 247 tu laptop bought brand nw last year
now 2 issues arise
its wifi gets limited connectivity first then disconnects and says no wifi available even wifi is on on my phone.then what ever i do it wont connects again and keep showing red cross on wifi icon .the only way to reconnect is restart the laptop.
during this disconnection my internet setting also gone non responsive and if i open internet setting it keeps on loading and very rarely opens and if it opens settings are un responsive
wifi button works fine but when this issue start this button alse become non responding

i thought it to be window issue as didnt installed window since i bought so did a complete reinstall by formatting c drive but same issue still here
i tried to installed every latest drivers but all in vain
any idea why it happens

2nd issue first it battery last for more then 4 hours continous use with full brightness but now battery wont last more then hour n half with min brightness?

does wired connection also giving similar problems ? please check that, else internal wifi must be busted although its very rare these things dont go bad that easy.

Battery is going down sir and needs a replacement, also please check temps if laptop is under constant stress that takes away battery aswell.

no it dosnt but what other option there is .. there is a shop in blue area right under media intl that sell good battery copies, I bought one for my toshiba and it laster a year and half with 2 hrs backup

Buy a cheap usb wifi device or as I said just for testing purpose use cable
