Well I'm really late to posting here but I keep running across this site and I've read the post here and some I agree with but I came to help, I have this computer DELL INSPIRON 1501 TRURON 64 BIT, THESE ORG. CAME with Sempron 64bit, I have 8 gig's ram and a 500 gig H/D, I'm running a dual boot win 7 win 10 64bit system.
This I bought brand new at Dell store, and I'm still using it everyday and it's never missed a beet.
So for the Win 7 system the drivers that are bit hard to get working are the Synaptic and ATI Xpress 1150 which I have working fine. The ATI 1150 i got from Dell R163595 run in compatibility mode for Vista in Device Manager it will show Ver. 8.362.0.0, date on it show 4/5/2007<, it's a 64 bit (you can use different computers for DRV) next is the Synaptic (Dell touchpad)ver.13.2.2.2, date 6/26/2009, R227597 or R228103 or R227835 in compatibility mode for Vista or try win 7 don't be afraid of EXP.
The driver's I first used were the XP drv. that were for the 1501 and ran in Compatibility mode and they also worked but I wanted some options for touchpad so I found different drv. the rest were very easy to get as they were for the 1501 or MS updated the drv, The hard one to get going correctly is Win 10 but so far it's working great, Except for touchpad its a bummer , I have one works in eveything except for EDGE, APP'S MENU AND START MENU , the other is ATI Xpress 1150,but I did finaly get that installed, you have to have dispaly adapter or you won't have SLEEP or HIBERNATE mode, I used the AMD ATI Vista drv for that so I'm happy, I'm not sure I like 10 but it does have some nice features like you can send TEXT message and call from the APP, but you could install them in 7. So I guess I've given what I have but if some of you are still here after 7-8 years I hope to hear how you r 1501 is doing. Ohya I'm using an AIR BAR , IT GIVE'S YOU touch screen which is really great , it works good in Win 7 and ifie in Win 10 , it does have the drv. for them, ( go to YOUTUBE ) type in air bar watch the demo, I really got it for my IMAC which I bought back in Jan 2007 when I bought my 1501 . SO good luck ...
