never go ACER either ... on all the desktop or laptop i had before going back into self assembled PC's ...
every HP did hold fine: 1 pavillon with 1035T/8gb/gf405/300w ok not the best out there but not bad either since the price was kinda low 4 SFF desktop 2 notebook
but every ACER i had went fubar ... 1 laptop on DAY 1! ... and the customer service said : corrupted SATA we can't do nothing, no refund, it might be your fault .... oh well i didn't know pressing the "power button" on the 1st start after getting it out of the box, would end corrupting the SATA... total BS, 1 screen ... 1 day after warranty : poof no image no more ... i still have my 24" 16/10 ACER P243W but the flickering and trembling at 60hz is awful ... it handle fine 75hz but i have to do custom profile for it ...
short mode : HP is better than ACER and it's not hard to do so ... ACER produce so many POS... (tho they do not so bad Android tablet)
for the rest indeed Lenovo/MSI/ASUS/Dell/Toshiba do better than HP
