Lenovo ideapad 305 disconnecting from wifi constantly

I have a Lenovo ideapad 305 which I have had for about 18 months. I have constantly had the issue where the laptop will randomly disconnect from WiFi and is then unable to reconnect. I have to turn the laptop off and restart it to reconnect the WiFi and it will then just disconnect again. I have previously sent this to Lenovo to fix but they wiped the whole laptop even when I asked them not to. 

 

I have uninstalled all the network drives for the WiFi and forgot all the WiFi connection and it still happens. Nothing else I use disconnects except this laptop. 

 

Is there anything else I can do to fix this issue?

 

Would advise staying away from Lenovo laptops, it’s been a problem ever since I’ve owned it. 

Safe laptop heat? Can’t detect fan?

So I just bought my Lenovo y520 and I updated to the new BIOS, somehow the OS got corrupted so I got it fixed after some stuff. Now with the fresh instal etc, I was playing Fortnite and noticed the heat was reaching the 70-80 range. What are the ranges for safe temperature? Also hwmonitor doesn’t detect my fans so what do I do?

Yoga 910 80VF Touchpad

This PC was working great until the last windows update was automatically downloaded (ver 1083). Now my touchpad won’t work.

 

Under the device manager I have an exclamation mark by one of the  I2C HID device’s. I am also not seeing a touchpad option in devices, all I see is a mouse one.

 

I have downloaded all the recent driver updates from Lenovo but that did not help.

 

I have also tried resetting windows but again, that did not help.

 

Has anyone else had this problem?

 

Thanks

W520 Dock Questions

So I have both a 433815U (04Y2071) and 433835U (04Y2074) dock. The first is supposed to be the 90W version which doesn’t support Quad Core W520. I bought both versions from ebay and the 04Y2071 seems to be working when I dock my laptop on it. Not sure what to make of it. Both docks have the wedge power connector. The 04Y2071 came with a 90W and the 04Y2074 came with a 170W.

 

Does the 90W dock just charge slower?

We will be happy to hear your thoughts
