Oh right that's not bad at all. It must be my memory failing me but I seem to remember my mates Game Gear absolutely draining batteries.

Oh yea stock they will destroy batteries - None of my systems are stock though
If you ever see me post a system chance of it being stock are slim to none 
- I just cant leave the bloody things alone.A stock Game Gear will melt a set of batteries in an hour, my modified GG (removed the 34v circuit and the whole GG runs off basically 5v) will last around 7 hours on a set of batteries while having a far superior screen.
Mine has lipo's and a usb-c charge circuit.
Like this (104050's 2x 2000mah in series using a s2 board)...
I wouldnt give a customer one back like this.. Id normally do a load of work on the batteries making them not look ghetto. There is one in this thread somewhere with a "customer version" of this mod.
After ive done the same sort of mods on the nomad I would expect it to last I dunno 8 hours or so, its already got the functional mods I wanted now so next up ill mod its power delivery with some internal Lipo batteries as long as I can find a way to fit them in the shell.
So far its just rocking a moden IPS and the ability to region switch from NTSC/PAL and EU/USA/JP.

Any idea why Sega didn't remove this 34v circuit when it was released?
Don
34v is needed by the original screen (specifically I believe its for the CFL backlight)

Oh right, that makes sense then

Aye back in 1991 the LCD tech wasn't even close to where it is today. To make a colour console they basically compromised everything in terms of battery to get something that works.

i seem to recall mine used to whistle as well. Possibly the step up converter?
Mine went on a cruise with a friend back in 1994 and never re-appeared

Was just a slightly annoying high pitch whine/whistle. Maybe it was because my hearing was still fully functional at that age?

I mean they weren't built to last thats for sure. Gameboys are somewhat bullet proof. The GG though there probably isnt a 100% stock working one anywhere on the planet that hasnt had a recap etc. Then the chances of a acceptable working original screen is like 1 in 10 or there abouts.

Seeing your process I'm pretty optimistic about my laptop lol.
Well I am back at home after another little holiday and ill be ready to crack it out
or at least try.@Journey - Guess what was waiting for me when I got here?
If you guessed 6 gddr chips from the fella in China for your 1660 or whatever it is you would be absolutely correct
Will slap em on it and give it a run in over the next few days. Dude even sent the correct ones first time...
No stencil yet for the other card but sure that will be here soon.

Just hope they don't all set on fire at first boot.
Looking forward to seeing the result!

Not sure what that means, but sounds in-depth!
It basically removes all the audio and video signals off of the motherboard onto a separate board and provides a ton of upgrades. It basically provides the following:
- Uses the latest THS7374 amp and uses bypass circuitry to improve RGB signal clarity.
- Utilises the Mega Amp 2.0 audio amp which vastly improves the audio compared to stock.
- Jumpers which allow you to choose between many audio configurations.
- Audio optimised with the MDFourier project to match the best audio quality that comes from a new Model 1.
- Low-pass filter toggle.
The 32x is already set up ready to accept any mods he decides to put into this and will auto swap regions based on whatever signal it receives. He has also provided a multi region bios chip with the mega CD 
The flash cart is also here to be unbricked..
