Lenovo G50-80 lappie and Win 7

VanguardLH écrivait :

Since the laptop is new, it should be under a warranty. Have you tried
calling Lenovo to report the problem?

Downgrading the OS might be a reason for an OEM to void the warranty.

Yep, they sell a pre-built product. They design the platform to use a
specific OS along with the drivers for the hardware in the product and
the OS they put on it. Quite often you find the maker has no drivers
for a particular model of their product at a lesser version of the OS
(and often not for later versions of the OS, either). That image or
state of the product is what they support.

However, for the product that he OP reported that he has, Lenovo does
support multiple product images or states. That is, they support
different versions of the OS than just the one with which the product
happened to be delivered to the customer.

http://pcsupport.lenovo.com/us/en/pr...0-80/downloads

That lists:
- Windows 10 (64-bit)
- Windows 8.1 (64-bit)
- Windows 8 (64-bit)
- Windows 7 (64-bit)
- Windows 7 (32-bit)

Since the maker will deliver drivers for Windows 7 (the OP didn't
mention bitwidth) then the OP should be able to put Windows 7 on that
laptop and have Lenovo support it. It's possible they provide support
based on ticket (purchase order) and that's the only config (as
delivered originally) that they will support. I build my own so I don't
know what Lenovo's support is like.

With all those OS versions listed on their support page, it's likely
that they sold this laptop model at some point with each of those OS
versions.

I would still call Lenovo. They may support that product with Win7.
However, although the OP never did say the USB ports worked under Win10,
if the OP reports to Lenova that the USB ports work under the delivered
config then it is not a hardware issue. It is a user setup issue, and
that means they may charge to fix the user's screwup. After all, they
support what they manufactured, not something different manufactured by
the user.

If the USB ports work under the Win10 image supplied in the product
delivered by Lenovo, the OP is here because he suspects Lenovo will
charge him for supporting a config that isn't Lenovo's. But you never
know. Calling them might be a surprising boon.

Simply stated the USB ports work well when booted under UEFI setting
in the BIOS but when I boot under legacy setting the ports do not
work. When I switch back to UEFI the ports work again.

So I do not think there is any loose cable etc. And audio works well.

Now I feel that there is a BIOS problem or Lenovo made it that way on
purpose.

It's the drivers, not the BIOS or OS. You bought a Win10 notebook, and
Win10 uses UEFI. Whether or not one can obtain drivers for that notebook
that work under its legacy BIOS is up to the manufacturer, so if they
have 'em, one can get 'em, if not, SOL. Still, I wouldn't be surprised
if there weren't other issue with trying to run an earlier OS on that
machine because the underlying OS code has changed even since Win8.x,
Win7 is structurally Vista 2.0, and with anything earlier all bets are off.

Archer has yet to identify what USB device he is attaching to which USB
port on the laptop. According to its manual, there are 2 USB ports.
One is identified as USB3 (blue). Presumably that means the other is
just USB2. Maybe he is trying to attach a USB3 device to the USB2 port.
We don't know what USB devices that Archer is trying to plug into which
laptop USB port. But then Archer has not stated that he installed the
device drivers for the USB-attached hardware. USB drivers are to define
that hardware interface, not the communications protocol to the device.
Maybe he is attaching a mouse or keyboard to the laptop's USB port(s)
which should use the native device drivers in Windows (assuming just a
simple mouse or simple keyboard) but we don't know. He won't say. USB
ports with nothing attached are worthless (unused) ports. USB ports
have no value by themselves. That he won't discuss the peripherals he
attaches (brand, model, USB type) and keeps focusing on USB support back
in the BIOS/UEFI (which does NOT have support beyond anything other than
legacy devices - simple mouse, simple keyboard) makes it appear he
thinks the USB driver is all that is needed to get a USB device working.

As yet, Archer has not stated that he installed Lenovo's USB3 driver.
When I go to the linke that I already provided to him, the description
of the USB driver is:

USB 3.0 Driver for Windows 7 (64-bit) - Lenovo G40-80, G50-80, G50-80
Touch

Presumably that means the USB2 port is support by native (included)
drivers in Windows. Windows 7 does NOT come bundled with USB3 drivers.
Windows 7 mainstream support ended over a year ago so Microsoft won't be
altering their installer to include USB3 drivers in the image for
Windows 7.

So far, Archer has not addressed any troubleshooting suggestions
mentined by respondents: has he installed the Lenovo USB drivers in
Windows 7, has he installed the USB *device* drivers, has he checked the
USB ports are not disabled in BIOS (MBR), what is he attached to the
laptop's USB ports. He just keeps focusing on the BIOS (which won't
support non-legacy USB *devices*) and Windows 7 (where he has to install
the USB3 driver from Lenovo along with the *device* drivers he attaches
to the laptop's USB ports). If he continues to be obtuse, he might be a
troll wasting our time. I'll give him one more shot and then I'm gone.

The install went very well but none of the USB work. I tried USB

on G50 laptop but could not get the solution.

Thanks to all of you for trying to help me on this issue.

As I said the 2 ports USB 2.0 and one USB 3.0 did not work when
working under legacy setting.

Talked to a Lenov guy whom I met accidentally who suggested the
following:

Remove battery and keep the power button for at least 30 seconds. Now
go to BIOS setup after connecting the battery and setup for legacy.

I did this and I am glad to say that the 2 USB 2.0 ports worked and
the USB 3.0 also worked after I installed the necessary drivers.

Thanks again to all

That's a hard reset aka power reset.

You didn't mention if you had customized the BIOS settings. Settings
are copied into a CMOS table. They can be misconfigured. They CMOS
table copies of the settings can also get corrupted, especially if the
CMOS battery (not the main battery) is weak.

http://shop.lenovo.com/us/en/laptops...series/g50-80/

A popup tells me that model is no longer available; i.e., it was
discontinued (but does not say when it was discontinued). I could not
find when this unit was first introduced.

How old is your unit? If over 4-5 years old, the main battery should be
replaced. They don't last forever as capacity diminishes over time (80%
loss over 2 years) and with each power cycle (400-1000 cycles). The
lithium coin-cell CMOS battery doesn't last forever, either, and should
be replaced at 3-6 years (some are better than others); however, that
battery is usually a bitch to replace as it requires disassembly of the
laptop's case. You might find a Youtube video to help with disassembly
or take it to a computer shop to have them replace the CMOS battery.

A hard reset restores BIOS settings to their factory defaults (by
reading the standard set from BIOS EEPROMs into the CMOS table). Often
there is an option within the BIOS settings to reset to factory defaults
(rather than have to force a clear of the CMOS table via power reset).

Thanks for the reminder about this troubleshooting step.
